I just purchased a Winchester 69 from a buddy for $100. It has both the .22 short and .22lr. magazines. It is a first generation model with the "safe" & "fire" bolt. I read that they were made from March 1935 until Sept. 1937.

In August 1935, the bolt was redesigned to incorporate a "rebounding firing pin". I have no idea what a rebounding firing pin is. How would I know if my rifle has the original style bolt or the "rebounding firing pin"?

Any and all assistance will be greatly appreciated.
