Thanks. I just looked at the one you posted and thats in far better shape. Good question you asked what number shoulderboards would go with it. Unfortunately I have too little post yet to look at the list but I am working on it
That set of straps is from one of the Banns created later during wartime. You would need a West Moselland triangle to match those. They appear to be a "slip on" set, not sewn to the uniform. If that's the case they could be changed easily.
Edit to answer your question all the Banns are included on the lists.
The Bann lists contain only Bann numbers and Obergebiet/Gebiet information and timeframe. Garry can be helpful with Bann names for individual inquiries.
