I have something similar, entitled Small Arms Manual by Lt. Col. J.A. Barlow, originally published January 1942. Mine is a 1953 reprint.
It covers vitually all the allied and axis weapons that a soldier was likely to encounter at the time, including Indy's Webley .455 & S&W .45. It's a great little book with an overview of each firearm with simple instructions for loading, unloading, firing, stripping, assembling and maintenance.
