The one circled in blue is not a Model 34. There is no adjustable rear sight and it lacks the shark fin front sight.
It would help if you had the serial number. Also, is it a .22? Maybe a .32 HE. That would allow a 3 1/4" barrel.
I think it might be an I frame and the extractor rod appears to be barrel shaped, which would lead one to believe it is from before 1947. Unless the picture is misleading. The stocks are post-WWII.
Edit: I see Gil snuck in before me (no adjustable sight).
It's a five shot J frame round butt so a Model 32 .38 S&W or a model 36 .38 Spl made between 1966 when the flat latch ended and mid 1968 when the diamond around the grip screw ended.
Was the model 32 or its variants offered with a 3" barrel?
See my post #21. In one of the other pictures you can see the MOD 36 in the yoke cut.Yeah, you can see the forcing cone in this photo

Definitely not a M34 - looks like a 38 caliber to me, so almost certainly a M36, 3" 38 special.
