This is a brass leadpipe for the Mt. Vernon 42 model, with a large bore, ordered directly from BrassArk. New reference price: 38,340 yen The threads are for Edwards, so it can be used with Getzen or Edwards slides. I used it for a short time, but I am selling it due to a change in the instrument I use. There are some minor scratches from attaching it to the slide, but there are no dents or distortions. Please feel free to comment if you have any questions about the product or would like to negotiate the price!
