There’s some Gunsmith images in the gallery which may be of interest:

I’ve just found a couple of new images this week showing some interesting attachments, the first is a sprayer exhibited at the 1950 Smithfield Show. The second from 1951 is a 5cwt tipping skip which could be lowered and emptied from the drivers seat.
