A seldom seen 1950's adapter that allows the firing of 22 caliber shotshells in standard 12 gauge shotguns. It was retailed by Abercrombie & Fitch and manufactured by the Barrelette Co. in Cranford, N.J. It is complete and in as new condition. It still has its' original Allen wrench to allow for proper tightening when inserted into the chamber. The built in ejector works in conjunction with the shotgun ejector. It fits any single or double break shotgun, but cannot be inserted into pumps, automatics or lever actions. In the original Barrelette box with the Abercrombie & Fitch retail label, ($10.00!), wrench, advert and ejector barrel. Where would you get another ?
