The Austrian Steyr-Hahn Pistol M1911/M1912

Production Information for the Steyr-Hahn

These pistols used the alphabetic letters sequentially, a,b,...x,y,z as a serial number suffix. That accounts for 260,000 pistols. There were a few exceptions or special runs of pistols. If WWI had lasted a couple more years I'm not sure what would have been used as a suffix after z?
