WWI BRITISH BARREL INSPECTION REFLECTOR TOOL

This was a new one to me and had to do some digging to find out who’s it was I kind of knew what it for but that was it. So after a short time on the internet its a WWI British scope to examine rifle bore’s. From what I have found this scope was for NCO’s as it had the attached arm to hold it while looking. The arm and cap are stamped with the Broad Arrow and the hinge is stamped with EFD for Enfield mfg. Condition very good +++
