Some new information about this horn. A prospective bidder pointed out that the horn has a Cleveland style neck and a Cleveland serial number but the bell says East Lake. I have had the horn since new and it has never had major repairs or modifications. We can only speculate that the horn body and neck came from the Cleveland factory, and that the final assembly and bell attachment was completed later at the East Lake factory. That makes this horn a very rare piece. Please feel free to contact me with questions and I will tell you what I know.
