A black Panzer wrapper. This type was only issued by Waffen-SS troops. It has no vertical seam to the back and is designed slightly differently to the front side as well.

All insignia are missing. You can cleary the see the shadow of a sleeve and and formerly attached collar tabs. You can also "guess" some traces of a breast eagle. Maybe a collector had displayed this tunic with Army insignia not know better that it is an SS type. There are three pair of award loops which were also certainly added by a collector after war. 

Silk lining. Size stamped and "F.4?" depot marked. "Dekawe ..." maker marked. 

A few moth bites but no serious damage. Nice condition.

Most probably worn by an officer once. Small shoulder board buttons as well as small size loops to attach officer's boards. 

Very rare!
