That’s correct. But according my informations this type came up for officers around 1915. Nevertheles, I have to correct the source where I have my informations from. I wrote an Essay about cockades for myself from various sources, when I started interesting for Pickelhaube. Unfortunately I lost the source and thought it was from a french book too, where I got other informations from, but it was an entry in a French Forum of our dear member clovis57. Hope he can tell us if he knows a book where the informations are fromThere is an officer Reichs kokarde with the center and 2 smaller holes for sale right now on A of K. To me this is designed for the M91 post and prongs to go through the kokarde and into the helmet.
