Ross M-10 bolt missing.

I wouldn't be surprised as the time in which they were made was much different to later. I'd think it might not be the best idea to just grab a bolt and get started...

You would want to check the headspace and the contact on the bolt lugs, using engineers blue for the latter.

I've wondered sometimes if the lack of bolt serial numbers on the Ross was due to their being interchangeable. That would mean a very high standard of manufacture and gauging. Of course they were built to a pretty high standard in both material and complexity. It's one of those things that is lost to history unfortunately.

At one time I had 3 Ross mkIII rifles. Two of them the bolts could be intechanged. The third one would not accept either of the other bolts. If I recall correctly, the third rifle's bolt would fit into one of the other two rifles, but not freely. Obviously, I did not check the headspace and was careful to get the bolts back into the rifle they came from originally. There was a lot more hand fitting in those days, as machining tolerances were not as precise.
