UBB.threads Forums Edged Weapons SA & NSKK Dagger Forum Carl & Robert Linder SA dagger

I would like opinions on the dagger I bought at the Tenn. Military Col. Show. It's an early SA dagger Gau Mark Wm (unclean, with a nice patina, just the way I like them). I'm wondering how rare the maker is and what's the image with the maker's name.
