Hello, I was trying to do research on this cap I received from my Grandfather which I believe was something my great-uncle procured and decided to keep while in the military. I tried doing some research on my own but came across this site while looking for information and thought maybe someone here could help me. Correct me if I’m wrong but I think based on the information I found on my own that this is a German Officer’s Peaked Cap Made by Robert Lubstein (EREL) and a Sonderklasse? Some of the writing in the cap I can’t read, maybe someone else can recognize it(?), but the name of the man who owned it was Adolf Marx.

I would love to know anything else I can about this cap, maybe even some ideas of where I could look to find out anything about the person it belonged to as well.
