Sad to part with this horn but I just upgraded to a Lukas. This horn has been professionally played in major orchestras across Asia, Europe and America. Professionally maintained and cleaned every year. Horn was purchased brand new in Japan in 2015, I am its only owner. Leadpipe rebuilt by the maker when I told him I bought this instrument, has an American bit receiver attached. Some minor dings from a mute in bell, will send photos if requested. 

I will include the two mouthpieces made for this horn by its makers. One is from Siegfrieds call and the Bruno Tilz Mouthpiece suggested by Martin Ecker

Its official description from the website:

Design inspired directly from an exceptional pre-WWI C.F. Schmidt "Weimar Berlin". The valve design and philosophy of this horn was influenced by Carl Geyer.

The original bell mandrel was discovered, purchased, and is being used - the bell is not a copy. The bell flare includes a copper plated steel wire, soldered in like they used to do it. The mouth pipe is from a successful original C.F. Schmidt pipe submitted to Dieter Otto through Lou Denaro and Dick Martz. It has been slightly modified to preserve tonal structure but improve intonation. All bracing is handmade from brass rods, annealed, further worked, and fit to each horn individually. All slides are hand-lapped brass inside and outside. The horn includes traditionally hand-bent tapered parts and branches.
