Thanks very much to all of you for the nice comments. I have indeed reasons to believe that this hat came to me in the same condition as it was stored away in 1918. The shellack has somehow melted and left stains on the Uberzug. I have always refrained from cleaning anything on this helmet. I did not even dare undoing the chinscales, and the cockades are stuck to the shell.
Tony, I know this is on your wish list... I told you a long time ago I would look for one for you, but I never saw another one. Joe, you are of course welcome to use the pictures. In fact I thought you already had these markings in your thread.

PS: referring to a recent discussion about gilding of EM plates, this one obviously had a nice "Versilberung", most of which is now gone.
