Bach 36 (near-mint condition)
Hagmann valve (Osmun-installed custom job)
Edwards .525" N slide (beautiful)
Everything about this horn is fantastic except for a subtle crazing of the lacquer on the valve section. I'm not sure what kind of lacquer Osmun used, but it's crazey. Get it?
Below is a description I received from the original seller:
One of the characteristics of a Hagmann valve is the valve bore and F attachment tubing match the slide. That is, for a .525" bore horn like the 36, the Hagmann valve and tubing have a .525" bore. Bach uses a .547" bore for their valve and F attachment tubing, on their 36B's. Similarly, on a Bach 42, a Hagmann valve & tubing would have a .547" bore like the slide. A Bach 42B valve uses a .562" bore and tubing ID for the F attachment. A Bach 50B uses a .578" valve and F attachment tubing ID, while the standard bass slide has a .562" bore.
Actually, what I have said about the stock Bach F attachment horns is not entirely true. The stock Bach valves lose some cross sectional area thru the valve. That is, a 36B's rotor might neck down from .547" to..530" on the way thru the valve. A 42B's rotor might neck down from .562" to .535" or something like that. I had several Bach basses in which the rotor opening necked down from .578" to around .550". Osmun has a routine that opens the Bach rotor back out to what it should be. The modification makes a significant difference. See "Open Rotor Ports" under "Trombone Services" at:

Osmun's surgery is impeccable.
If you are seriously interested (and not simply inquisitive), send me an email. My email is the first letters of this little poem:
Said you wanted a horn,
Like the one you played when young,
I told you to MAKE AN OFFER,
Perchance you shed a private tear.
Have a tissue, fellow bonester,
Or a box of junior mints.
Remember, the PM system causes much grief.
Never trust in it!
