Hi
just won a very early wooden stocked Crosman Powermaster 760 type BB/pellet rifle.
I already have a Pumpmaster with a rifled barrel I installed myself so I know these can be very accurate rifles.
This older model has a metal receiver and brass turn bolt type probe.
It looks to be complete and aside from surface rust near the muzzle the finish looks pretty much intact.
It probably needs new seals, if soaking with ATF doesn't revitalize the old ones.
Any information on these and any special steps or parts needed to reseal would be appreciated.
I've resealed my other 760 so I've got the general idea of what should be inside, but I seem to remember the exhaust valve firing mechanism may be different on the very early models.
Is it a dump valve, similar to the Daisy 880, or linear hammer actuated like the later model 760 rifles?
