Pretty informative although it ends rather abruptly. Guess there is nothing beyond the valve disassembly? Mine has one of the rear sight screw retaining holes stripped (right side looking down barrel). I am comtemplating drilling it out to next bigger SHCS. I dont believe the threads are stripped on the screw and there is very little material in the tube. Probably enough for maybe two screw threads. All in all still a good job on this old warhorse. I also have to open the grip screw holes on the stock as there is some misalignment. I can either do that or dremel the inside bottom of the stock to allow it to shift the screw holes up about .125 (1/8 inch).
Need more of these videos posted for us "old school" ballers as there is not a lot out there on some of these old markers.
Definately two thumbs up on this video!!!
