Horn Mouthpiece G. Seifert Model (Copy) I was given a copy of Mr. Seifert's mouthpiece a long time ago. I used it for a long time with a rim change, but I don't use it very often anymore, so I'm selling it. It is made of solid brass. ⚫︎Please note that this is only the cup for sale! Photos 7, 8, and 9 with the rim show a TAD DN (inner diameter 17.5mm) attached. The shank fits slightly into the mouthpipe of a German-made instrument, but I personally didn't mind using it. (See photo 10) Cup shape: Moderate U-cup Depth: About the same as Schmidt No. 8 Bore diameter: 4.3mm Please understand that this is a used item that has been stored by an individual, so please purchase only if you agree. Please check the size and condition of the dirt in the photos beforehand. [Please refrain from ignoring comments and silent transaction messages] #HornMouthpiece #Mouthpiece #Horn #Seifert #Horn
