Vintage benjamin sheridan pgp .68 paintball pistol

The gun is complete but not functional. The previous owner tried to undo the valve without having the tool to unscrew the valve and messed up the threads and the valve itself a lot. The valve is no longer in the right place and the screw in front of the trigger is no longer aligned with the holes in the valve and it no longer holds.
