Picture is a two-piece officer''s visor cover for junior grade from my collection of Kriegsmarine antiques. The cap has a hand-embroidered gilt wire national emblem and, cockade, as well as gold wire piping. This cap belonged to Werner Wendt (1916-1988), Captain of U-765. The U-765 was sunk in the North Atlantic on 6 May 1944 by depth charges on its first war parol. Werner and 10 crewmen survived, 37 dead.
Pictured below is the underside view of the visor cap.
Pictured below is the two-piece visor cover disassembled. In this configuration, a white or blue cap-covers could be worn. Because I do not like to take this cover apart, I used a photo taken years ago.
