Vintage Crossman Air Pistol w/Pump BB Gun Leaking Seal Possibly

Description

Vintage Crossman Air Pistol w/Pump BB Gun Leaking Seal Possibly. So for parts or maybe can be fixed. It seems to leak from a seal when pumping it, but can't say for sure if it can be fixed, so consider it for parts it what I am selling it as. Everything else seems like it wants to work. Was my dad's, worked up to a few years ago. Please look at pictures.  Thank you for looking and let me know if you have any questions.
