Don't know but it might be a Model 0f 1953 .22/32 kit gun "pre-Model 34".

Serial number seems to fit a very early one first made in 1953.

This is what I got from the 3rd edition SCS&W.

flat latch, diamond on the grip, adjustable rear sight

That one looks to be a five screw and the kit gun was a three or four -so like I said....,

don't know

edit: I just read this kit gun did not have the trigger guard screw so your's might be a four screw if no trigger guard screw.

built on the improved I frame.

Nice looking snubby.
