This is the Rank Badge as worn by a Flight Sergeant on his Right Arm. See the next Listing for the second one to make up a pair. "Quartermaster's Comment":- I thought of listing them together---but 'Sod's Law'---you would have only wanted the one!!! This item is in excellent condition and does not look as if it was ever mounted up for wear. See further comments per listings 1442 and 1444. Note also that this one is on a square backing, while the next one has been cut to a 'V' at the bottom.
