Yep. Pity they scrapped most of 'em after the war. Of course, that makes those that still exist worth a lot of money. So of you ever see something in grandad's closet that looks like a cheap, chinese-made stamped steel capgun, it might actually be worth more than that box of old records you had to move to get to it.
From what I am reading, they are pretty much disposable. After 50 rounds they are no longer safe to fire. They were designed to take a Nazi out so you could then take their gun.
In 1942 and accounting for inflation, they were only $26.
The originals are only good as relics. They don't make many reproductions for a reason.
