Just picked up a Model 34 (no-dash), 22. Ser.# 602**
Love to know the year
As noted above, it is c. 1959, but since they were not shipped in serial order, that is only an approximation.
It's a J-Frame, round butt.
As others have noted, it is built on the I frame, not the J.
However, it is not, as stated in the SCSW, the "Improved" I frame. Rather, it is on the "New" I frame, introduced in 1953. The difference is the length of the grip frame. No .22/32 was ever built on the Improved I frame.
In c. 1961, all I frame production was discontinued and I frame units were converted to the J frame. For the Kit Gun, this meant the Model 34-1 designation.
The barrel length on yours could be either 2" or 4". The butt could be either round or square. Any of those is desirable.
This picture displays two variations. The nickel unit is a Model 34-1 (J frame) with the round butt and 4" barrel. The blue unit is a Model of 1953 .22/32 Kit Gun (I frame) with the 2" barrel and round butt. The latter shipped in January, 1958, and is not model marked.
Edit: Jim snuck in a post while I was writing mine.
