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.

I have several 312 s but one has no serial # and on end of barrel theres a band that appears to hold the barrel tip in place....not sure if this was added or original, also has 2 piece bolt....does anyone know?
