Just browsed through my collection of German literature on the subject would appear that both Alder and also Hüller used the name "Orpheus" for both saxophones as well as "Blockflöte" (Recorders). Both were located in "Vogtland" Oscar Adler in Markneukirchen and G.H. Hüller over the hill in Schöneck. gruss - spike
P.S. sorry for my several posts and "Ediths" but I keep finding new info on the subject. I really need to catalogue all the info I have on this subject. It's mostly all in German and sometimes it's conflicting information not only that it's become scattered over nicks and crannies, boxes and bookshelves in various rooms of the house.
Just a quick thought - are there any more numbers stamped on the horn besides the serial number ?
P.S. Check the neck or the collar at the top of the body tube - there may be a number engraved or stamped on either or both of those areas.
P.P.S. I'll keep diggin' in my Archives - I keep finding bits of paper with scribbled notes:
"During the 1930s, G.H. Hüller could have been described as the largest saxophone manufacturer in Germany. At the time they were building more saxophones than Adler. G.H. Hüller models at the time were the: Imperial, Artist, Olymp, and Orpheus."
