This is a Bob Reeves Flugelhorn mouthpiece, model 42HF. The cup is considered quite deep. It should be a great match for solos, etc. I used it with a Yamaha flugelhorn, but it was a little loose, so I had to insert it a bit more firmly. I'm not sure if this is due to individual variations. There are minor dents and scratches from use, but nothing noticeable, and I think it's in relatively good condition. However, please understand that this is a used item.
