Matching bolt. Bayonet lug is there. I would be interested in the proof test. Please enlighten me. I will get more pics though.
I would like to see the rear of the receiver if you get the chance to photograph it. Is the rear sight in place? Is it adjustable or just a flip sight? Since it is matching and the receiver has not been messed with then I would restore it.
To proof test an old milsurp do the following.
Go to the range when no one else is around.
Bring a saw horse and some ratchet straps.
Strap the rifle tightly on top of the sawhorse and point safely down range.
Tie a 50 yard string onto the trigger.
Load the rifle.
Very carefully walk back 50 yards being careful not to pull the string hard.
Get behind cover like a rock, building, tree etc.
Pull the string firing the gun when your body is not at all exposed and no one else is around.
Examine the gun and the spent cartridge. If the gun is in pieces, the gun was not safe to shoot. If the gun is solid and undamaged and the spent case still retains the original shape of a 303 and shows no signs of excessive pressure then the gun is still in 303 and safe to shoot.
This is easy in ME as I can just go to a sand pit. Not sure what your options are in MA to do this safely.
It is the redneck way of doing it. Just make sure you are real careful because if the gun fails big time there will be shrapnel.
BTW... my advice is worth what you paid for it. You bear all the responsibility for your actions.
Just be real careful please.
