This, and all the other replies have been very helpful. Thank you. Sorry, though Badger, I didn't see a No. 1 SMLE listed in the Canadian Knowledge Library. Am I missing it somehow?
The reason I'm curious about the markings is that I've come across a couple of L-E that I'm quite interested in. I've only had time for a cursory glance at both, but plan to take a closer look soon.
The first is a '44 Long Branch Mk I* - all matching in great shape, but I didn't see any C-Broad arrow markings in my quick scan. Possible? Quite common? And what does the lack of such markings indicate?
