the tool in the pic is a very simple version, only a grip with a hole you slip over the pin to extract the case with it. the tool in the drawing is much more sophisticated.

aaron, you have an interesting website, find it with google but you can set link to your site here.
do you know the data collection made by a german collector ( I think name was M. Strecker) in the 1990s about pinfire pistol and shotgun cartridges? there was probably no cartridge he dont find for his work.

such a corkscrew tool exist also for early Dreyse needle fire shotguns in the same time period.they were shooting a paper cartridge with a base made from rolled paper that seal the barrels. the paper case burns when fired or leave the barrel through the muzzle. the base was removed with the tool by hand before you load an new round.
