I found a frank holton sousaphone at a pawn shop and bought it for 50 bucks. I can't seem to find a serial # on it i was wondering if any one knows where it is located on the horn or date period maybe. The Engraving says Frank Holton elkhorn Wis the # 122 between the name and plant. If your wondering it plays like a dream a sound that makes me wish i could literally play it in a concert band.
