Hi all.

I’ve been handed a couple of “bits and bobs” and wonders if anyone has knowledge of the old H&N White New Proportion trombones

This one looks to me like it may have been “extended” at the tuning slide (maybe a shift to low pitch) and has a small bell. Likely 7 inches I think.

I’m not a king expert at all. Any ideas??

I don’t have the slide (it’s basically a clear out).

With a bell lock this is a relatively late instrument. Possibly the predecessor of the Liberty. You might want to see if a 2B slide fits.

There is a lot of information on older King models on www.hnwhite.com
