Crosman Model 99 Air Rifle, Lever Action Pellet Gun, Co2 original scope 1965-70

  
Crosman Model 99 Air Rifle, Lever Action Pellet Gun, Co2 original scope 1965-70. Lever action, cocks and trigger and hammer all function. When I tried to put the CO2 in it, it continued to leak rapidly so maybe the O-ring fell out or went bad where you load the co2 cartridge possibly. I'm sure it's an easy fix. I just don't have time personally to repair it. Such an awesome, rare old. 22 cal pellet rifle and you don't see these old lever action CO2 rifles around anymore, getting rarer to find. All the wood is in great shape couple little marks but nothing deep. The gun is in great shape.
