Different type of pistol than what is commonly encountered. Outwardly it resembles a semi-automatic Colt Woodsman; in actuality it is a manually operated firearm that must be cycled by hand after every shot. Chambered for .22 rimfire and offered with interchangeable barrels in lengths of 3", 7.5" and 20". Also offered a detachable buttstock. Finish is blued and grips are found in both smooth and ribbed walnut. Rear sight is a square-notched blade that tips up into an elevation-adjustable peep sight. Marked "Fiala Arms and Equipment Co. Inc. / New Haven Conn. / Patents Pending" on right side of frame behind grip and Model 1920/Made in U.S.A. on right side of frame above trigger guard. Left side of frame marked "FIALA ARMS" above image of polar bear with "TRADE MARK" below polar bear in area above trigger guard. Pistol furnished in one of three variations of cases that were optionally available: canvas case, black leatherette case velvet-lined and fitted with a lock and key, and tan leather version of leatherette case. A fixed 7.5" barrel variation was also produced. A 7.5" smoothbore barrel was cataloged as a silencer. Some 20" smoothbore barrels were produced. Some pistols bear the names "Columbia Arms Company" and "Botwinik Brothers". Government has classified this pistol with its stock as a "Curio or Relic" and in its complete state a very desirable collectible. NOTE: See also Schall & Co.
