I love old Olds horns and have 2 L.A. Ambassadors , one of which has the fastest valves of any horn I own. I think it’s worth noting, and certainly a testament to the quality of the Olds product, that the valve section on Uan Raseys Olds horn was the one used in the Ambassador. Robb Stewarts website has a page dedicated to Uan - it’s worth a read. As I understood it, Olds was a “one tolerance” shop, which means all their instruments were made to the same tolerance specs regardless of price. That’s pretty incredible.
Sincerely,
Ron
