this gun  is from my child  hood  and  has a scope base 
the base broke the solder between barrel and pump
also seals seem to have gone bad
the gun  is 40 years  old  but  i want to raise it from the dead
anyone have an  address where it can be  fixed  and   what  do things like that  cost??
how does this gun compare to some of the newer stuff?
i  used to get complete penetration on 1/2 inch plywood  and squirrels
