Kriegsmarine Coastal Artillery Officers Collar Patches

A scare pair of Kriegsmarine Officer’s Collar Tabs for wear on the field grey uniform.
Although generally associated with the Coastal Artillery the field grey uniform was initially issued to all branches of the Kriegsmarine but later issued only to the Coastal Artillery or when needed by other specific land based branches.
The collar tabs feature hand embroidered litzen in bright silver aluminium wire threads with gilt wire centre stripe. Mounted on a feldgrau wool base.
Condition is very good with slight oxidisation to the silver wire.
Very hard to find.
