I own one of these. Appears to me to perhaps be a wartime manufactured Maltby(maybe) that got it's original markings scrubbed off the left side and new RFI markings applied to the right butt-socket to include serial number.

I've never seen another Indian No.4 quite like it and really didn't realize India issued the No.4 rifles in enough quantity to re-manufacture them. So what's the story on RFI No.4 Mk.I rifles?

Thanx Ht
