Hello Everyone. I won the bid on a 1948-50 L.A. Olds Ambassador trumpet Ser#27668 at a auction for$20.00 The lead pipe reciever is damaged. But can be fixed by my local music tech. I thought about doing a mod. change out on this lead pipe. I have considered a Pilczuk lead pipe. They come in brass, rose brass, and Silver. What would be the best choice. And would the horns intonation and playing be that greatly improved? It has low set valve stems and buttons. It has two star guides on each valve guide instead of one on the fullerton models.It feels much lighter and better balanced than the fullerton models. Would you believe all the slides pulled with no probs. Compression still good and valves shiny. The yellow brass seems to have a well tempered look and feel to it.I know it is no Recording. But I like all the Olds trumpets and cornets. Especially the L.A. models.
