This video discusses the various styles of revolvers manufactured by H&R during the period beginning around 1900 through the 1980′s including the final production run of these revolvers by NEF. The four main styles of revolvers produced by H&R included the solid frame, the top break, the swing out cylinder, and the old western pattern (modified solid frame). These revolvers were constructed with three forms of lock work over the years. The first form of lock work was the free wheeling cylinder type demonstrated in the video with the “American Double Action” and early 922 models. This pattern of lock work was modified in the 1960′s and 1970′s to incorporate a new cylinder locking bolt which eliminated the free wheeling cylinder. This modification was present in the late model 622 shown in the video. All types of revolvers were later modified to incorporate a modern type of hammer block safety as shown in the 926, 733 and NEF production guns.
The video discusses which parts interchange between the various patterns of revolvers and identifies parts commonly missing from used guns.
