Reproduction Waffen - SS Totenkopf collar tabs.
1) Totenkopf Collar Tabs - Vertical
In 1940, the men of "Totenkopf" began wearing what we call "mirrored" collar tabs, which were collar tabs featuring a "Totenkopf" on both sides
They were issued earlier than the horizontal type. However, right-facing skulls are generally earlier than left-facing skulls.
2) Totenkopf Collar Tabs - Horizontal
Vertical Totenkopf Collar Tabs was changed from "vertical" to a "horizontal" orientation in 1940
By 1944, the mirrored collar tabs were gone, and most men were issued "horizontal" style
4) RZM Collar Tabs - Mid War style
5) Pumkinhead Collar Tabs - so called pumkinhead or pirate skull characterized by long protruding bones are generally thought to be early to mid war vintage, although they were discovered in small numbers at the Dachau Clothing Works in 1945. Although not manufactured there.
6) Dachau Collar Tabs - so called Dachau type, this is very late war variant (End of War)
For a period of time from October 1939 until May 1940, when the collar rank insignia was reintroduced for wear, dual insignia were authorized. After May 1940, the use of the dual collar insignia was forbidden, but a number of personnel continued the practice until late in the war.”
