So in a box of stuff from my father in law's attic I've come across an odd magazine. It has "P-38" engraved roughly by hand (probably by my father in law). I know he had a P38 but it's long gone. It held the fifteen rounds I had handy from a G19 magazine and seemed like it might take one or two more. Worth anything? Sorry if this is the wrong place, but I couldn't find any similar magazines online so I thought I'd put it in general firearms.
