King Slide Compatibility

[ithinknot]

Does anyone know if a 3B slide will fit on a Selmer Bolero bell?

Don't know about the tapers, but the nuts/threads are on opposite sides, so that part of the equation is a definite no

Has anyone modified a .525 slide (non-King) to fit a King 607F? I've got the horn, but it has the unfortunate restrictive leadpipe. I know that a 3B+ or Benge 175 slide would work, but there are not many out there. I saw that Aidan modified a 607 slide to accept another leadpipe, but it looked like a lot of work. Anybody try, say, a Yamaha .525 slide (with swapping of tenon, nut, etc)?

Or, is there any reliable way to tell the older 607 slide (with better leadpipe) from the newer, without a close-up examination?
