1919A6 heads up
Treat this weapon as if it is loaded, if you cant retract the bolt you have no idea wether it has a round in the chamber or not! I wouldn't be beating on anything from the muzzle end, before determining if the chamber is empty, one could slip something like a piece of stiff wire like a (coathanger straightened out) down the barrel mark the end remove it and lay alongside the barrel to see if the chamber is occupied a .30'06 Ball round is about 3 1/4 inches long, so it will be easy to determine if a round is in the chamber. Also, you have no idea of the position of the firing pin, it could be stuck forward!. You need a good penetrating oil to soak it in, if you can find some Kroil, or other penetrating oil it will do a better job on loosening up the parts diesel is ok but has too high a viscosity to soak into small areas. How much have you disassembled it, IE backplate removed?. Be careful of the drive spring rod, if it comes out of the bolt you could be in a world of hurt. Is the cocking handle missing completely or broken off in the bolt? If broken off, it might be binding in the sideplate slot. Another thing to check, turn the weapon up side down there id a screw in the bottom plate that holds the unlocking cam on the inside in place this screw should be staked in place about 1/4 turn from hand tight. if too loose or missing the cam may have shifted and could be jamming the bolt in a locked position. look into the in the opening in the bottom plate where the empties dorp out and see if the unlocking cam is in its proper position.
After determining that the chamber is empty, you could remove the barrel shroud locking screw and try to unscrew the shroud from the trunnion (reciever) Some shrouds have been soldered to the trunnion and you may have to heat the shroud to get it to move.
Thanks for doing what us old fat guys cant do for ourselves, your service is deeply apreciated!!
