[Trombone-l] "Convertible" trombones

[Keith Marr]

I'm interested to know how many models there were that enabled the player to convert from straight tenor horn to one with trigger in the days before the inception of modular horns like Edwards, Rath and Shires.

I have a Boosey & Hawkes Sovereign 547 from the 1970s which uses the old German idea of housing the trigger in an alternative tuning slide. Speaking of old German trombones I have an old Wolfram which converts in the same way.

I know that there must be many old German examples of this idea going back to probably the late 1890s or even earlier, but what I'm interested in is American style trombones that had that facility.

The only one I know about apart from my old 547 is the Conn 89H which had an F trigger in a replacement gooseneck I think.

I'd be interested to know if there were any more and if so what system they used to facilitate the conversion.

Cheers!
