Data from "Consolidation Goods Loco, Bombay, Baroda & C I Ry", The Locomotive Magazine,Vol XIII (14 December 1907), p. 212.
This class of Consolidations was derived from the HG design drafted by the British Engineering Standards Association (BESA), but had cylinders measuring 1 inch greater in diameter.
Data from "Recent Locomotivdes by Messrs. Arrmstrong, Whitworth & Co., Ltc, Locomotive News and Railway Contractor, Volume XI [11], No 5 (10 March 1922), pp. 146-149. Works numbers were 69-93 in 1921.
The LNRC report was based on an AW catalogue released in 1922. The AWs repeated a 1908 Ten-wheeler order from Locobase 10633, but increased cylinder diameter by 1" (25.4 mm). (The 1908 engines were based on a BESA design, but had increased cylinder diameter by 1".)
