I recently picked up this old Arsenal de-capper, with instruction sheet dated 1909. They were provided at small unit levels for use in creating gallery practice ammo. The device handles .38 and .45 pistol, and .30 rifle (Krag and '06) cases- and everything in between. By removing the decapping pin you can (carefully) re-cap with it too. Everything is intact in the case, including the small funnel and cleaning brush, as well as the full compliment of spare de-capping pins. I had one many years ago and had despaired of ever finding another. When I spotted it setting on a table at a show I was on it like a chicken on a June bug!
