Hi Dean, usually it should have the "stem" on the top. It might have been cut off.
There is absolutely nothing wrong with your beret tam. It is the most common type, if any can be called common. Here are two specimens done in the more subdued silver/gray embroidery. The SS insignia is zig-zag stitched on, while the Heer insignia is straight stitched. So far there are only a couple of known examples of the gray Heer insignia originally mounted. The tam is also stamped 1940.
The crash helmets do pop up for sale every once in a while, but usually go fast.
Great berets shown in this thread. Here are mine.
I am seeking Golden Party Badge # 77578, Luftwaffe blue summerweight flight pants, used Geschwader Immelmann officer's cuff title.
As a practical matter, I do not understand how the Pz men were able to make do w/o the beret. An M-43/Schiffchen/Visor cap aren't going to give you any %age of protection as compared to the Beret.
Must be simply that German penchant for style over practicality!
