treblig1958, there is no way to remove all of the oil from the wood without disassembly. None, nada, neyt. Sorry. 30 years of refinishing gunstocks for others has revealed inletting of older guns can be stubborn and "hold" oil for a long time. Some even get tougher than PA24's time line. I have just finished a Blair SxS which took four months to stop bleeding oil in the head area. Each time I thought it was gone...black spots reappeared. One just has to keep at it until it is gone.
