Hi Kman, I've emailed you.

considerably less in germany, concidering third reich insignias are illegal there

Actually the public display of the swastika is illegal, but private ownership of extant and reproduction Third Reich items kept from the public eye is not. Museums displaying these historic relics are an exception. There is a wide audience of WWII German militaria collectors world wide, Germany included, that would be interested in marked horns of this type, as well as the collector looking for out of the ordinary examples to fill his collection. You are honestly likely to get more from the former rather than the latter collector monetarily. This would also depend on whether the markings are for a political group such as the SA NSKK etc., or a military branch such as the Luftwaffe, Heer, or Kriegsmarine. I have yet to see an SS marked sax, and doubt seriously that one exists, as Hitler's condemnation of the instrument and Schräge Musik (Jazz) would be followed to the T by both the Allgemeine and Waffen SS more than any other organization., exceptions from other branches/groups such as your example and others of it's ilk notwithstanding. If you are at a quandary who to contact to sell this, let me know and I can assist you.

yes please, I would not like ot sell it at all but as I am in need of money I feel quite compelled to do so. If you can assist me I would be very grateful. together with Huller Alto Sax I also have a Franz Muller silver tenor sax from Bremen but I have found no literature about it. it should be of the same period with no SS indentification. I am located in Italy. where are you writing from?

I'm located in the Nashville area of the US. I will send you links to contacts I have that will help to put you in touch with interested buyers. By SS, I mean SchutzStaffel as in Waffen SS. I wouldn't expect yours to be marked as such, as I do not believe that such examples ever existed. Your horn is a Luftwaffe (airforce) marked example by the way.
