I always have post this by Glenn handy when I come across Beamte Pickelhauben. IMO its very valuable information and as far as I've seen no one has ever contradicted it.
"Square peak "dragoon style":

* Intendance officials with the equivalence of general officers' rank wore a general officers' helmet with the small gold shield of the officials beneath the Guard star. Extremely rare I would have thought!

Hope this helps everyone interested in the subject as much as it helped me. Again, thanks Glenn.

Here is my Beamte Helm that I've had for some time, he must have been a big boy because it fits my bucket not that I wear it around the house when doing paperwork.
