Benjamin made this model from 1946 to 1985, but did not start serializing them until 1957. I also have a Benjamin Franklin that has no serial number. Before 1957 it is not possible to set an exact date. Just know it's OLD. The 137 is a .177 caliber pellet pistol the 132 is a .22 caliber pistol and the 130 is a BB pistol.
It would be worth between $60 and $80.
I have a Model 101-22 Cal. L.R. SN 10467 that I will sell for parts.
GUNPARTSCORP.com and JACKFIRSTGUN.com carry lots of parts.
SOME (not all) parts are available from gunpartscorp. Check their website.
