Hello All. I'm brand new and clueless and on the lookout for help or advice. I have been given a load of old stuff, included within which, was this trumpet: It says on it; "Olds Ambassador Fullerton Calif" Also, similar, is this trombone, which also says "Olds Ambassador" on it. And this trombone that says nothing on it. Anyone got any ideas on value, or shall I just keep them as fun ornaments? Many thanks in advance.
