As pictured in various reference books, this is an original war era SS officer cap eagle.
A Very Rare SS Eagle by M167.
It is the best example I have ever seen and comes as it was found in a Veteran's "stuff", many years ago.
As usual the lower ( and virtually impossible to install on an already assembled cap) prong is missing.
The prongs appear undamaged and good to me, but I am an insignia guy and would never start bending prongs!
In a world of SS eagles which are turds, this is your chance to get the real thing.
