KOSIKUP REGD Cornet Mouthpiece, made in England. Probably for a short cornet. It's definitely old, but there isn't much information available. I don't know the size, but the inner diameter feels small. If you know about these, please consider it. There is distortion on the shank end. - Brand: KOSIKUP - Model: REGD ⚪︎⚪︎ (Unreadable) - Country of Manufacture: ENGLAND Thank you for viewing.
