I have a No.5 that is all matching however, the rear sight is of the correct type 800yd variety but is marked with a B on the major parts would that make it a BSA item? I got the rifle at a good price in great condition the only draw back was it had been drilled for scope and later had the screw holds plugged which could be a deal breaker for some, the BNP proof didn't get clobbered when drilled and whoever plugged them did a fairly decent job it is an early rifle it's dated 9/44. I was kinda thinking if it was drilled for a scope and latter plugged someone had enough foresight to replace the rear sight with the correct type but didn't know the difference. I want another No.5 this could become an addiction.
