    First off, there is no such air rifle as a "Benjamin Franklin". It's in quotes because it was a play(joke) on the company name. "Benjamin Air Rifle Company" which you will find on the end cap.

    What you have is a Benjamin model 312, these rifles were built from 1940 until 1969.

    The 312 is a .22 and when repaired, it should shoot just as hard and accurate as the newer 392 being sold today. >The model 342 was built from 1969 until 1992

    There are a number of people who work on old Benjamin pumpers, and you can buy parts for them as well.
