Hello, I'm all new here, so I'm hoping no one will fuss at me for posting in the wrong thread. ^.^ Can someone please help me determine the date of a trumpet that I have acquired, and possibly give me an estimated value? It's an older Olds Ambassador, the only number I found on it is #857652. I'll include some pictures so everyone can look for themselves. Thank you so very much for your time and patience. Hope everyone has a fantastic day.
