    At the moment, my piston Bb is a Monette Prana3 and my C is a Bach 229H, so EVERYTHING is different.

    If we take 2 "standard" Bachs (a model 37 and a 229H) and compare them:
    the C has a more fluid "creamier" sound. The Bb is more brazen, with a different type of edge when pushed. The C sound is perhaps "clearer". In any case, what happens to the overtones when playing a crescendo is much different. The Bb gets a much different type of edge - starting at lower volume levels. The strings start to complain sooner with the Bb as the edge means more overtones and that masks what they hear.

    I have a B flat Monette 993 and my C is a Prana1. They are very similar. I might not be a good enough player to feel all the subtle differences. Given what I have to work with, Two really good trumpets and OK playing, I think I could cut down the B flat to C and it would work.

    You have a huge difference with a Monette and a Bach. I could cut down my MF Prana but it would sound different than the Prana 1 because it's so much lighter. Still, I think it would work in C.

    My 50th birthday is coming up. Maybe I'll ask the wife for a ticket to Germany. What do I do if she makes it one way?

    I'll add this...for a time, my C trumpet was the best horn I owned. I needed a better Bb, so I reasoned "Why not just buy a set of C/Bb conversion slides for the C?" I did (Bach Strad), and while the converted trumpet had an "interesting " sound, it didn't play very well. The mouthpipe and bracing was all wrong with the longer slides. I ended up buying a good Bb and selling the slide set.

    An old teacher of mine did (does?) have a horn that he can switch between Bb and C,
    but it was a tunable bell horn, with a removable leadpipe. You had to readjust the horn and couldn't easily switch back and forth, but that horn could definitely play in either key

    Schilke C trumpets with Bb slides play very well.

    As you shorten or lengthen a valved brass instrument to change from one fundamental concert pitch to an adjacent one, the amount of tubing which needs to be added by using a valve needs to be shortened or lengthened accordingly. As you ascend in pitch the relative change per half-step is the same, but the actual change in slide length becomes smaller, and slides can be pulled out a bit to work in the lower key.

    The difference between C and Bb in one horn, a whole step (duh), calls for a considerably larger change in slide length than the half-step between D and Eb on one horn, in which every length is already shorter because of the higher fundamental. The higher you go, the easier it is to build a horn which can be played in adjacent keys. Conversely, going lower ends up requiring the implementation of elaborate concepts like double horns, and compensating systems - to get the valves to yield good intonation for an instrument built for just one key.

    Here is my opinion:
    If it seems to good to be true
    It probably is...

    I wouldn't buy an convertable horn, not matter who manufactured it.
    That may just be me.
