Our house hold loves these little revolvers. Here's two of our three, both with original finishes.
Identifying these is kinda like keying out the species of a plant or critter. So correct me if I'm wrong:
1) Both are post-1949, when the 2" barrel was introduced.
2) The nickle piece has the newer style bolt spring so it lacks the trigger guard screw....a post 1953 Improved I-frame....and also lacks the upper sideplate screw....post 1956. But it also lacks a Model #, which originated in 1957....so it was made between 1956 and 1957?
3) The blued piece has the trigger guard screw...pre 1953....but also has the newer-style coil mainspring, which was spose to have been introduced in the same year with the improved I-frame. Yet it's an older I-frame, with a grip frame about 3/16" shorter than the nickle piece. A betwizt-and-between piece from 1953?
Downright sporting.
