    I am wondering if the valves on any bach model 43 trumpet would be interchangeable?

    I would think that as long as they are the same bore size, they will fit. Send Charlie Melk, or Jim Becker at Osmun Music an email. They will let you know for sure.

    Theoretically, as all valves 'should' be lapped to their valve housing, valves should NOT be interchangeable.

    That's what my tech says. I'm 50/50 on valve swapping. I put a replacement set in my 1951 Ambassador, and they've worked fine. I tried a swap for a 1960 ambassador from two different parts horns, and it did not work. Had to break down and send it to Anderson's to have the valves re-done. Of course, if it works it can save hundreds of $$.

    that's a tough one. depends on the age difference of the horns, how the players push down the valves. if a doner trumpet is played with the valves pushed down with the middle of the finger it would be worn in the casing differently than a player that pushes the valves straight down with fingertips.

    No, because the casing size is different, but if you use the wrong kind, you could end up with air leaks. But, I've never seen a different valve go into another trumpet...:dontknow:

    i think he's talking about another trumpet of the same year, make, and model
