CORP 5C without a dot From the early Elkhart era. There is evidence of use on the rim, shank, etc., so please examine the images and purchase with your understanding. From a well-regarded era, It has a warm tone different from current models, and the comfortable blowing experience is wonderful. I am selling it because the rim didn't suit me, but I think it's a very good mouthpiece. (Shipping is not available from December 26th to December 28th, 2025. Shipping will be on December 29th. Please understand.)
