... from a King 3B fit on a King 3B+? To be clear this relates to me looking to put together a valve trombone as opposed to adding a trigger. Any guidance appreciated.

I am just curios. How would a tenor with an F-attachment do what a valve trombone could do? Just to clarify, I understand how an instrument with valves would have certain advantages/disadvantages versus a slide instrument However, for a valve trombone to work like a slide trombone with an F-attachment would it not have to have a 4th valve like many euphoniums do??

The slide tenons are different on the 3B and 3B+.

On the F-side, all the (3) valve loops would be too short. Like insisting on using the 7 Bb slide positions on the F-side of a trigger trombone. Ouch.

An F-attachment on a conventional valve trombone would be like an uncompensated 4 valve euphonium. You can approximate some of the notes, but all valves will give you a somewhat sharp low C. 1-4 would be close to Eb, 3-4 would be close to D, 1-3-4 would be close to a Db.

I have always wondered: Why are 4-valve valve bones common in Europe but rare as hens' teeth in the US?...
