Data from " Goods Locomotive, G & SW Ry,", Locomotive Magazine, Vol XII (15 November 1906), p. 190.
This class was a bit bigger than the standard goods engines James Manson was already operating on the G & SW.
Later updated with a larger boiler; see Locobase 20863.
Data from " Glasgow and South Western Locomotive Rebuilds", Locomotive Magazine, Volume XXVII [27] (15 September 1921), p. 225.
Locobase 10594 describes James Manson's six-coupled goods locomotives delivered in 1906. Robert H Whitelegg's update centered on the large boiler also used in the rebuilt 4-4-0. A significant visual difference in the new boiler was a smaller steam dome set back to sit over the middle coupled axle.
LM also reported the installation of "much improved type of cab" and added "...it is understood that the general efficiency and economy has been greatly increased by the transformation."

Data from "New Shunting Engines, Glasgow and South Western Ry," Locomotive Magaziner, Volume XXIV [24] (15 February 1918), p. 22.
Peter Drummond, the Central London's locomotive superintendent, designed this trio of shunters. In an unusual variation, the engine's valves were actuated by outside radial gear. The balanced Richardson valves were lubricated by an Eddlewood mechanical lubricator.
Data from Ahrons (1927).
Patrick Stirling designed these two goods engines, but they obviously proved unsatisfactory as they were the last ones he designed for 11 years. Ahrons implies that the outside-cylinder layout, which was very rare, may have been the source of disaffection.
Boiler pressure is an estimate based on other G & SW engines of the period.
