New to me SHT LE III*

[SA M1Dom]

Somehow or another. We started with Ross rifles but that didn't work out, troops picked some up and then we started procuring them properly. By the date of this rifle we'd have been getting them through supply networks. Yes, built in EFD...UK. Now, good luck finding the 1907 bayonet that's equally marked. They do show up occasionally though. Someone tell me again what that R in front of the C broad arrow is for? Rust?

I'm just happy there are matching serial numbers on the bolt and nose cap. I would imagine it was re-barreled though the rifling is very sharp and nice bright bore. Looks new. So I guess there is a good chance this old warhorse saw some time in the CEF during WWII
