It appears that at least four of these statues were made by Messrs Coade.
One is at Ham House, another is at Terrace Garden Richmond another Moor Park, Herts.
Another was at the Bleach Works, Llewenny (Lleweni) Hall, Denbighs, before 1789, but disppeared many years ago.
Alison Kelly notes
John Bacon exhibited a ‘Figure of Thames, Colossal’ at the Royal Society of Arts in 1777, for which he received a prize. This presumably referes to a model / macquette.
This was most likely an early version of the River God.
He also produced a macquette for an "Ocean" which is very similar to the River God here but in reverse - this was probably a model for the bearded figure on the Monument to the Earl of Chatham in Westminster Abbey of 1784 - A Bronzed Terracotta Modello for the Figure of Ocean in
the Clratham Monument, c.I778.

At Lleweni the River God appears to have been paired with the naiad.

Given the dedication to Prince George, Marquis of Buckingham it was perhaps used unsuccessfully to entice him to use a version at Stowe.

The Ham House River God / Father Thames.
The version of the River God at Ham House was installed at
the front of the house by Wilbrahim Tollemache, 6th Earl of Dysart, between
1799-1803, when the north front of the house was opened up to the river. A
watercolour by Thomas Rowlandson dated 1803 shows the River God in situ before
the house (see below).
"The model at Ham House can
be dated more precisely, to 1779, thanks to the coat-of-arms on the front, in
which the badge of the City of London is accompanied by the Cap of Liberty and
the City Chamberlain’s purse, both on sticks" (Jeremy Warren - Nat Trust website).
These motifs refer to the radical
politician John Wilkes (1725-97) who became City Chamberlain in 1779, and who
is depicted in the celebrated engraving by William Hogarth published in 1763
holding a stick with the Cap of Liberty.
Evolving from the ancient headgear
known as Phrygian caps, the Cap of Liberty came to signify freedom and the
pursuit of liberty, firstly in the American Revolution and then subsequently in
the French Revolution.In the same year 1779, as part of a competition set by
the City of London, John Bacon the Elder made six designs for a splendid
Freedom Box presented by the City to Admiral Keppel (designs in Victoria &
Albert Museum, box in the Museum of London).
Something of a political statement if one reads between the lines!

The Richmond River God / Father Thames.
Coade's Artificial Stone.
Article December 1993 from Context -
After years of neglect, the River God by John Bacon has been
completely restoredand resited in a prominent position in Terrace Gardens,
Richmond. The restoration of this important Coade stonefigure was carried out by
conservators Taylor Pearce, the £15,000 project being funded by an appeal initiated by the
Richmond Society.
The one ton statue, which took pride of place in Mrs Coade's 1784 catalogue, was originally purchased for 100 guineas by the Duke of Montague
for the pleasure gardens he was then laying out. The subject of an etching by
Blake, only three other versions of Bacons River God survive according to Peter
Locke, architect and advisor to the Richmond Society. "Its one of thefinest pieces
made by the Coade manufactoryand its importance is increased by its rarity." It is also the largest Coade work every cast in a single piece. Of the three figures, one, in Coade,
stands in the forecourt of Ham House; another, a bronze, is in the courtyard of
Somerset House; and the last, in natural stone, is located at Powerscourt in Ireland.
The
Somerset House bronze was used by Taylor Pearce as the pattern from which to
reproduce a missing left leg, rightfoot and hand.
One interesting discovery was that the leg circumference of
the bronzefigure was 2 mm larger than the Coade one, due to shrinkage of the clay
in the Coade preparation of Bacons casting process. To account for this a
delicate adjustment of the master casts had to be made from the bronze and, to
give the cast items an authentic Coade appearance in keeping with the rest of the
piece, a cement-based mixture of various sands was used.
The figure was first steam
cleaned to remove over 200 years of disfiguring carbon deposits but not the
pleasing patina of age.
Restoration work involved the removal of rusting iron cramps
and their replacement with stainless steel, as well as the removal of some earlier
and unsympathetic in-situ restoration work. The original plinth of the statue was
restored and a new foundation for it was prepared at its relocated site in
Terrace Gardens.
Instead of being tucked away just off a pathway in the gardens - a position it had occupied since 1902 - the statue now commands a central position on a
hillock in from of an imposing hedgerow in the park.
Relocating it presented a considerable logistical problem
far Taylor Pearce and fine art handling specialist Momart, who was responsiblefar
transporting the statue in specially designed air suspension trucks. The problem of
getting a one ton statue onto a base at the top of a hillock which is surrounded by,
and consistsof soft soil is considerable. The problem was resolved by taking the statue
off the truck outside the park and transporting it on a trolley over scaffold boards
laid like tram lines to the one spot of level ground around the area - which was behind the hedge at the top of the hillock. From there it was winched over the hedge onto
its plinth. A time capsule was enclosed in the base incorporating an account of the
project and the names of the donors.
In view of its importance the statue has also been
ringed by a security system

Terrace Gardens, Richmond is now a public park created through the merger of the grounds of three houses, Buccleuch House (demolished 1936/38), Landsdowne House (demolished 1869) and Cardigan House (demolished 1970).
The grounds of Buccleuch House and
Landsdowne House were initially consolidated by the Duke of Buccleuch in the
1860s and became a public park in 1887.
The grounds of neighbouring Cardigan
House were added in the 1920s. None of these houses is still standing but the
C19 layout of their gardens is still very much in evidence.
Sizes - H 157 x W 236 x D (?) cm; Plinth: H 87 x W 212 x D 89 cm.
The land on Richmond Hill was originally clay pits and brick works.
During the period 1765-1771 parcels of land in this area of Richmond Hill were acquired for George Brudenell, the Earl of Cardigan and Duke of Montagu.
The land purchased consisted of a parcel on the riverside west of the Lower
Road (now Buccleuch Gardens) and included the Tile Kilns / brickworks and the wharf, as well
as adjacent plots to the east of Lower Road.
The coat of arms on the figures are those of the city of London. This
figure was originally purchased by George Brudenell, Earl of Cardigan, the Duke of Montague in 1781 for his house
on the site of the present day Buccleugh Gardens and was placed in
the Pleasure Gardens nearby.
Horace Walpole said of a visit in 1790 that '[the garden] is
perfectly screened from human eyes, tho' in the bosom of so populous a village:
and you climb til at last, treading the houses under feet, you recover the
Thames and all the world at a little distance. I am amazed that it is not more
talked of'. In 1796 the house and gardens were described by Daniel Lysons: 'At
the foot of the hill the Duke of Buccleuch has a villa ... It is situated on
the banks of the Thames. From the lawn there is a subterraneous communication
with the gardens and shrubberies on the opposite site of the road, which
extends almost to the summit of the hill. They are laid out with taste and have
local advantages to most places of the kind in the kingdom'.
The house was demolished in 1936 - 38.
In 1887 the Vestry acquired the existing site and
opened what is now Terrace Gardens to the public. The original position of the
work is unknown, but it was discovered in the early 1990s buried in a nearby
patch of undergrowth in a neglected state. In 1993 it was restored and reset as
part of voluntary community project by the Richmond Society on behalf on the
London Borough of Richmond on Thames with the help of grants and donations from
numerous organisations and individuals.

The Moor Park Coade Stone River God.
The recently rediscovered Moor Park River God lies semi-hidden at Moor Park at Rickmansworth. Although
headless and armless it is recognisably the same as the Ham House river god,
even to the Code signature nestling inside.
It appears to have been moved to
its present position in a 19th century shrubbery during a remodeling of the
gardens by Lord Ebury and was still intact when the mansion was sold to Lord
Leverhulme in 1919 to convert to a country-club come golf course.
Lady Susan
Grosvenor returned to her childhood haunts and described ‘Neptune’ as being
‘brown with age,…, head engulfed in a Portuguese laurel’ but with water still
trickling from the pitcher in his hand (though it looks more like tucked under
his arm).

Coade at Lleweni (Lleweny), Denbeigh.
Clipping from - The British Architect 30 April 1875.
The statue of Water mentioned here must be The Naiad no. 18 in the 1784 Coade Catalogue.
..................................
A slightly later version of the water nymph, by now called
Sabrina and dated 1802, is at Croome Court. (National Trust - (NT 105007).
One of Capability Brown's greatest achievements was the
creation of an artificial serpentine lake that meanders for 1.5 miles through
the estate's central valley.
The Croome Lake is a scaled down 'model' of the
Severn River, which marked the western boundary of the estate.
Sabrina takes
her name from the nymph spirit of the Severn.
The grotto in which she was placed was originally
decorated with exotic shells, coral and gems and supplied with water from one
of the branches of the culvert drainage network. This water was directed through
a pipe in the grotto and flowed from the urn held under Sabrina's right arm on
to the banks of the lake below.
The Coade Naiad was commissioned from Coade at
Croome Court, laid out by Capability Brown and which is described in an 1824
guide to Croome by its gardener William Dean:
"Beyond the Grotto, appears the
figure of a Water Nymph, reclining on the bank, and holding an urn - through
which, the waters, collected from a copious spring, at some distance, are made
to flow, in a perpetucal stream, falling among pieces of broken rock; and
afterwards mingling with the waters of the lake".
This water nymph represents
Hafren (Roman Sabrina), supposedly the ancient spirit of the river Severn.
According to Alison Kelly in Mrs Coade's Stone. The Croome Court Naiad was not
far from the Severn, and either Mrs Coade or John Sealy showed some literary
knowledge by referring to the figure, in their handbook, as Sabrina, the nymph
of the Severn in Milton's Comus

to his son Sir Robert Salusbury Cotton, 5th Baronet, who sold the property;
In 1776 Lleweni leased to the Hon. Thomas Fitzmaurice MP
(1742-1793), brother of William Petty, 2nd Earl of Shelburne, Prime Minister of
Great Britain for £110,000.
The 1810 notice of the sale of the estate runs as follows:
"The very extensive and valuable FREEHOLD ESTATES
comprising the noble Mansion of Lleweny Hall, which contains ample
accommodation for a family of the first distinction, together with a new
erected and very commodious bleach works, water corn-mill, and iron forge, all
well supplied with water, a public-house, and several improvable farms: the
whole containing near 4000 acres of extraordinary rich meadow, pasture, arable,
and wood land, in a high state of cultivation, and lying nearly in a ring fence"
Sold to William Hughes in 1810 for £280,000. Hughs demolished the major part of it and used some of the elements for building Kinmel.

A Page from the Mark Blanchard Catalogue.
Mark Henry Blanchard was born at Portsea, Hampshire and
christened on 30 August 1817. He was apprenticed at the Coade Factory in
Lambeth in the firm's declining years, probably when it was managed by Thomas
John Croggon between c.1835 - 37, or after the business had been let to Thomas
Routledge and John Danforth Greenwood 1837 which endured until 1840.
Blanchard commenced business in Blackfriars Road, Lambeth
shortly after 1840 (probably working initially in plaster) and then appears to
have acquired some of the Coade Factory's moulds when Routledge and Greenwood
consigned them at auction in 1843.
Note the continued use of a varient of the Coade engraving
in Blanchards promotional material (below) and the mention of John Bacon as
designer.
