Hi guys. Thanks again for the help. I found a website with some diagrams of most of the tools for 1916 through to about 1948 for future reference
http://1940chevrolet.comI've managed to get a good part of the tools off eBay in one lot, aside from the tire pump, jack and oil can, but I'll keep my eyes open.
I've seen a few canvas bags on eBay as well. Was the original bag like the one sold from Jim Carters -
olive coloured canvas ? I'm assuming the gmc and chevy tool kits were the same, as well.
