Water Feed. The last 25 tenders were fitted with Drummond's exhaust steam heaters which were inside the well of the tank and were supplied with exhaust steam from the locomotive. The tank was clad with false plates, to prevent heat loss and blistering of the paintwork. Whilst the system did give a slight improvement in both coal and water consumption it was expensive to maintain and this was one of Drummond's frills which his successor, Robert Urie, removed. The cladding seems in virtually all cases to have not been removed.
Front side plates. From 1913 onwards plates were added underneath the front handrail stanchion supports. On the tenders with narrow spaced stanchions the lower edge of these plates was on top of the sandboxes whereas on the tenders with wide spaced stanchions the plates went outside the sandboxes down to the front platform.
Lamp brackets. The tenders were built with Drummonds socket style brackets. The SR standardised on a design with the socket in the lamp. Many tenders had the Drummond brackets adapted to accept the standard lamps but gradually many the tenders were fitted with new brackets of standard design.
Couplings. Most of the tenders appear in their early years to be running with a single long coupling link, although some carry three link couplings. Later the tenders were equipped with screw couplings together with a hook to carry the coupling when it was not required.
Widening of front platform. After 1923 the front of the platform was widened to 8' 1" to match the platform of the wide locomotives.
Coal shovelling plate. This was added from an unknown date; certainly by WW2.
Coal Rails. From circa 1936 onwards the coal rails were backed by metal sheeting to stop the loss of small coal.
Wheels. 3’ 7”, 10 Spokes with 5/32” axles, Slater’s Ref 7843SWMF.
