I have up for auction 1 Olds Ambassador Cornet with case and mouth piece. The cornet is in working condition. The valves work smoothly and I played it and it works fine. From a cosmetic perspective overall I rate it an 8 out of 10. It is generally pretty good cosmetically but one of the tubes has some dents in it which I took picture of. The slides work fine as well. It would make a great piece for restoration or someone starting out
