RTR Royal Tank Regiment Cast Brass Collar Badge as worn by Band

A cast brass collar badge (same size as cap badge?) with tank facing to the right as worn by members of the band. With original loops. Despite other ranks being issued with a tank facing left from 1925 onwards, this pattern with the tank facing 'the wrong way' continued to be worn by members of RTR band until at least WW2. Circa 5cms tall. Comm BoHa (367)
