Maintenance Manual and Illustrated Spare Parts List 15- and 20-cwt GS Trailer

[Ed Storey]

There were the following SB manuals for the 15 and 20 CWT GS Trailers:

SB-4 Gas Welding Trailer - 1943
SB-4A Gas Welding Trailer - 1944

SB-5 15 and 20 CWT. General Service Trailer - 1944
SB-5A 15 and 20 CWT. General Service Trailer - 1945

There were subtle differences in the manuals although I'd have to go and fish them out to determine exactly what they were. One of the most obvious differences between 5 and 5A was the illustrations and I have attached one as an example.

WRT the welding trailer, which was a companion to the KL Lorry, I believe some of the kit from the truck was moved back to the trailer, which may have changed the layout of the trailer necessitating a new manual. It's been a while since I had that stuff, but I think the blacksmiths box and the welding screens may have moved.
