There are the same kinds of issues in the collectible firearms community. Certain German Mauser 98 rifles from the years between WWI and WW II bring big bucks, if they have the correct "Waffenampts" (inspectors' cartouche stampings). There's a big business in reproducing the stamping dies used to create those markings, which can turn a virtually worthless "Russian Captured" Mauser into a high dollar collectible. "Buyer Beware!"
