I collect the Gasser-Montenegrin rounds, so this “experimental” seemed like a nice addition, and I got it at the SLICS auction. Unfortunately, I can’t seem to find any solid information on it. The headstamp is: V / 72 / GR / 18 /. Damn, I suck with a camera! Any help appreciated.
Can’t relate this to any specific gun, but the headstamp indicates the cartridge case was made in May 1872 by Georg Roth A.-G., to the best of my ability to interpret the headstamp information given and shown.
