Re: world war 1 pistols.
I would have thought the bottom of the barrel would be used copies of the American cast-zinc automatics - the Ravens, Lorcins, Brycos, Jennings, etc. Or maybe the cheap German revolvers of the 1960's and 70's.
The Ruby pistols get points now for being 75 to 100 years old, and having an association with WWI. Nobody with any sense wants to shoot them any more, but they are relics of a bygone time and place - and one of the few inexpensive gun collecting fields.
