British Tongue for Two Piece Buckle

UP1094. British made tongue for a two piece buckle, this is a buckle I'm not familiar with, I showed it to several of my dealer and collector buddies and the consensus is pre-war militia but some thought it was post war, I do know it was found in Mobile, AL, it is heavily made, the belt loop is 2.25" tall, disc diameter is 1.25", the design is very similar to an early rifleman button, either way a cool military tongue
