My father was a professional musician in NYC for many years. He fronted his band and played at Roseland, Lincoln Center, Barbara's, The Village Gate, and many other places. His main instrument was the sax, but he also played trumpet. He died 3 years ago and now I am selling his horns. His trumpet is a Wondertone Professional # 38756. I've not been able to find any info on line about this horn. It has pearl buttons and a case. Please let me know if you have any info and/or know anyone interested in buying it.
