Yacht-Car (JK) French Horn Mouthpiece Stefan Dohr Model 2E/DM 4.2 I purchased this new and used it for a while, but I'm selling it because I switched to a different model. There are no major dents or scratches on the rim, etc., but please understand that there are insertion marks on the mouthpiece pipe and minor scratches from use. (The following details are quoted from the internet) A U-cup with a depth between 2DM and 2EM. Throat is 4.2mm. (Additional Information) European shank!
