Reising .22 Cal. Auto Pistol
Manufactured by Iver Johnson's Arms & Cycle Works, Inc., of Fitchburg. Mass., the Model 66 Trails-man revolver with 6" barrel was introduced in 1958. Chambered for the .22 long rifle cartridge, this 8-shot, top-break, double-action revolver features a rebounding hammer and adjustable target sights. Chambers are counterbored to enclose the cartridge heads, and front face of the cylinder has a flash shield to direct powder gases forward and away from the shooter. Cartridges or fired cases arc ejected manually by depressing the ejector rod under the barrel. The
Model 66 Trailsman revolver with 6" barrel is optionally available with one-piece plastic or walnut grip.
From 1960 until 1964, the Model 66 revolver was offered with 23/4" barrel under the designation Trailsman-Snub (Snub Model 66S). In addition to cal. .22 long rifle, the Snub Model 66S Trailsman revolver was chambered for the .32 S&W and .38 S&W center-fire cartridges, (cylinder capacity 5 rounds)
In 1962, the Model 66 Trailsman cal. .22 long rifle revolver was offered with AVi" barrel. This version was discontinued in 1964.
INotc that the 2% " barrel Snub Model 66S (B) is provided with the smaller two-piece grips (39) and single transverse grip screw (37). The standard model (A) with 6" barrel has one-piccc grip with thumb rest (38). Grip is secured by a single screw (36).
2 In reassembling lock mechanism, replacing trigger guard (29) in frame is facilitated by using a small slave-pin (as shown at ('A') to secure scar and sear spring (25. 26) in rear of trigger guard. Make the slave-pin of brass rod or wood, slightly shorter than width of trigger guard. With slave-pin in place, trigger guard can be replaced in frame (18) with sear and spring and trigger guard pins (30) replaced. As rear trigger guard pin is drifted into frame, it will push slave-pin out.

Though the Davis-Warner "Infallible" was made in 2 distinct variations, it is a comparatively scarce American pocket pistol. This is probably due to the fact that it was a clumsy, bulky design. When compared with its contemporaries, the Colt, Remington, or Mauser, it had very little to recommend it. In shape and workmanship, it resembled some of the lesser known Belgian pocket pistols such as the Melior or the Feil. It is generally found either blued or with a mottled-color finish, and always in .32 cal. ACP.
While Davis-Warner magazines resemble most common .32 pistol magazines in outline, the row of holes and the notch in the back-strap are distinctive features.
Another distinctive feature Is the overlay construction used to make the magazine. This construction leaves an edge of sheet metal showing along the backstrap.—E. J. H0FF-SCHMIDT

Deer hunting is an interesting thing that reminds you of those golden old ages of 19th centuries, where a handsome hunk well equipped with all hunting material rides on horse searching for his target animal either for the purpose of displaying his masculine powers or for enticing and wooing his lady love.
