Benjamin Franklin 310 age and analysis?

[gben]

     A neighbor of mine sold this to me. I never had a Benjamin before. I can not find any serial number on it to check against factory records for age. It does not pump up or do much of anything, seals and more must be shot. I am wondering if it would be a good enough shooter and enough of a collectible to be worth putting time and money into.

Any old Benji is worth putting back together. In working good shape you will see them sell between 100-175. Obviously toward the top in if in great working condition. I notice your missing a couple parts, but most of it is there. You need a seal kit that will run you 35 bucks. Couple more bucks to get the missing parts. If you don't think you can rebuild the valve I can help get it going. PM me if interested.

PM me if interested.

 Sir is there any way to tell what age this rifle is even though it is lacking a serial number?

It's before 57 obviously. The fixed rear site and the safety design makes it closer toward 52ish. Let me PM someone he's good on the dating. I'm better at the tinkering and modding.
