Dear John
This is part of one of my papers for the Smoothbore Ordnance Journal possibly in Issue 3. It outlines the plans of British Ordnance that I have collected over the last five years. Sorry for the length of this but I thought you needed an almost complete answer.

Since the 1850s, the Victorian scale drawings of 1846-68 have been reproduced to represent the carriages that were used during the Napoleonic Wars. John Franklin's wonderful draftmanship in his book on the British Artillery is based upon these. These Victorian carriages were constructed by the Royal Carriage Department using water then steam powered machines. The carriages of the Napoleonic Wars were constructed with hand tools. Shuttleworth (c1820) Cadet Drawings show many differences in detail including a cruder constriction using hand tools only, different wheels, and the elevating screw is attached to the cascable to the Victorian drawings that have been traditionally reproduced to represent British Napoleonic Artillery.

Bracket Carriages (1760-1813)
The older Congreve bracket carriages and rolling stock that were used during the Seven Years War (1756-63), American War of Independence (1775-83) and y the Foot Batteries of the Royal Artillery until they were replaced by the Desaguliers system by late 1813 are shown in Muller (1780) and Rudyerd (1793).
• John Muller (1780 rp 1980) Treatise on Artillery, 3rd Edition John Millan, London [Reprinted by Museum Restoration] does not show the ordnance or carriages used during the Napoleonic Wars but was still an Official Text for the Cadets at the RMA until the 1820s.

Charles William Rudyerd like all Cadets of the Royal Military Academy at Woolwich had to draw the ordnance as part of the Artillery Course. [See the introduction to Adye (1813 rp 2010) published by Ken Trotman for further details upon the Royal Military Academy]
• Charles William Rudyerd (1793 rp1970) Course on Artillery in 1793 at the Royal Military Academy, Museum Restoration Service, Ottawa, Canada. He shows equipment that saw service during the Seven Years War and American War of Independence with only one plate of a Blomefield gun tube marked as “Draught.” This was soon replaced by the Blomefield designs in the mid 1790s. Alas this does not show any of the carriages and block-trail used by the Royal Horse Artillery.
• R.W. Adye (1801-27) Bombardier and Pocket Gunner alas does not have any drawings. [1813 (7th Edition) is reprinted by Ken Trotman]

Desaguliers Block-Trail System (1793-1820)
There are a few contemporary French and German drawings that show British block trail carriages but these are in the collections of the Musee de L'Armee, Berlin, and Copenhagen. The British Experimental Horse Artillery were using them from the 1780s and this continued when the Royal Horse Artillery received its patent in 1793 before the introduction of steam-driven machinery and refinements to the Royal Carriage Department that started in the 1820s. This gradually replaced the older M1778/1788 Congreve bracket carriages and vehicles with the introduction of the M1805 Blomefield 9-pdr to the Foot Artillery that was only complete just before Waterloo in 1815. [See the discussion in DDS (2007)]
• Cadet Ashton Shuttleworth (c1820) Cadet Drawings [Kane List No. 1711] that have only been reproduced in McConnell (1988).

M1825 Block Trail
The annotated drawings of Cadet Mould (c1825), Spearman (1828 & 1844) and Griffiths (1839) alas do not have a scale and are produced to show parts of the gun. These including the scale drawings of the Prussian officer Captain Jacobi of the Prussian Artillery (1835) show the next generation of carriage and elevating screw that no longer connects to the cascable.

Mid Victorian Block Trails (1846-76)
Most authors have assumed that there were no changes from 1793 to 1846 when the first scale plans of the carriages by Nelson were produced for the Aide Memoir to the Military Sciences in 1846 (1st Edition) and again in 1853 (2nd Edition).

• Clerk (1853) in Aide Memoire 2nd Ed with plates dated 1844-6.
• Straith (1852) Treatise on Fortifications and Artillery, William H. Allen, London shows scale drawings of the wheels and axles [Plate XII], 9-pdr, limber and ammunition wagon [Plates XIII-XIV], 8in Howitzer carriage [Plate XV].

• John Henry Lefroy (1867) The Handbook for Field Service, 4th Edition, J.M. Boddy, Woolwich [1st Edition was published in 1854] with its Royal Carriage Department plates have been most commonly reproduced as representative of British Ordnance in the Napoleonic Wars by modern authors. However, there are a number of differences.
• C.B. Le Mesurier. (1868) Notes on the Manufacture of the Royal Carriage Department, Royal Arsenal, Woolwich. Revised Ed. shows the Victorian construction of wheels [Plate II-III & XXII], block trail [Plate VI], elevating screw [Plate VII], limber [Plate VIII]

Scale Plans of Ordnance
Contemporary plans of the Ordnance still show a great gap between those of Rudyerd (1793) who showed ordnance from the American War of Independence (1775-83) to Straith (from 1830s) and Boxer (1854).
• Rudyerd, C.W. (1793 rp1970) Course on Artillery in 1793 at the Royal Military Academy, Museum Restoration Service.

Allen, London [Reprinted by DP&G] shows scale drawings of the Iron 8in & 10in Howitzer, 12-pdr Howitzer, 24-pdr howitzer and 6-pdr [Plates XII]. BP Hughes (1964) considered Straith (1852) “the best available scale drawings … which were in service during the Crimean War.”
• Boxer, E.M. (1853) Vol. I: Diagrams of Guns referred to in Treatise on Artillery, HMSO shows the Blomefield Light 6-pdr, 9-pdr and Medium 12-pdr in the form that was used in the Napoleonic Wars without the Dispart Sight [Plates XIX-XXI] but not the 5½in Howitzer that was obsolete by 1825.

I hope that assists.
