Joe,
According to Bobba these guns are found within the range of 2000i to 3500i. They are long-frame, grip-safety style guns. The guns were rebarrelled by the H�¤mmerli firm in Switzerland with 4 3/4-inch, .30 barrels and roll-stamped with the "Abercrombie & Fitch" barrel legend. They were then imported by A&F. Conventional wisdom has it that this was all intnded as a deception to get around the Stoeger import monopoly of the Luger pistol.
There are questionable variations of the A&F marked pistols having to do with barrel length, caliber, barrel legend, and serial number.
There is a discussion of an unusual A&F pistol going on right now on Jan Still's Luger forum,
