Looking at a long branch that appears to have never left Canada. I cant find any markings on it that it was sent overseas but the bolt doesn't have a serial number on it. Any one ever run into this? Sorry I don't have any pics of it.
I am assuming that you are saying the bolt never had a serial number? Versus now having none because old one ground off? From the serial number of the receiver, or on the scroll on the left side, should be able to identify the year that the receiver was made - could be 80 years ago?? A spare, unmarked bolt could have been inserted by anyone (military or other owner) over that many years? Might want to check the bolt head for over-turn, and then check the headspace. If both lugs are bearing within the receiver, and the other two checks pan out, should be good to go?
No markings on the bayonet lug I believe he wrote. The marking by or on the bolt is probably the combined L B symbol
