Pair of diamond-shaped OT Collar Tabs (Kragenspiegel) as intended for enlisted man in the OT - 'Organisation Todt'. The OT was established in June of 1938 when the Inspector General for Roads, 'Dr. Fritz Todt', was tasked with the construction of the 'West Wall'. This is a pair of EM's collar tabs as introduced in 1943. The 'OT' monogram is machine embroidered in red on a olive drab wool backing. Nice original set in very good condition!
