This is a stainless steel mouthpiece made by Houser in the USA. Rim is not included. It's the Landsman model, with a deep V-cup and a bore size of 12, American shank. It shows some signs of use, but overall it's in good condition. The rim is the same as a Giardinelli. The response is extremely good, and it should suit a Kruspe-type instrument. No claims, no returns accepted.
