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.

Iver Johnson Revolver Joint Screw

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.

Melior PistoleInfallible PistolInfallible Pistol

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.

One of a series

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
