mnrivrat - Your guess as to DOB is probably right within a year. The 4th screw was deleted in 1955 and the frames were not stamped Model 34 until 1957. There were over 135,000 Pre-Model 34's built so they are not particularly hard to obtain. What I can add is you have a real nice looking gun in excellent condtion. Value I would say about $500-$600. Nice condition .22/32 Kit Guns seem to always command more money.
