I don't think it would be a problem: safety wise, to reunite the rifle and correct number bolt. Most of these rifles never fired a shot in anger nor probably fired more than 10 rounds a year in their lifetime. I also doubt it they were even used for parade looking at the butt plates. I suspect they sat in the amoury at "Pump Handle Sask." (mythical place by the way) and never saw the light of day.
