I am currently In the process of creating an impression of Imperial German Marine Infanterie. (More specifically, 2nd Marine Infanterie Regiment.)
So far I've located everything I need, except for a few things. My main concern at the moment is acquiring Litzen. The issue with this, is that no-one seems to produce or know anything about Marine litzen, let alone litzen in general.
Any information you have on litzen would help me tremendously. Patterns, fabric, sewing tips, literally anything. I know it'll be difficult, but if I can I intend to make a set myself If I can't find someone who makes them.
Below, I have included examples of the Litzen in question. They are off-yellow with a feldgrau center.
