Nope, just a plain ol' valve trombone.

Scroll down to see the trombonium.

Although described as "I believe it to be in key of Eb but not sure (NOT a Bb horn)", I am guessing that it is in Bb high hitch.

There is an extra loop in the tubing which goes from the valves to the bell connection (which is where the actual tuning slide is). The first bow in the mouthpipe appears fixed. Tonk imported his horns from Europe.

Trombonium was the trade name (King) for a specific marching valved trombone. This link explains it:

William Tonk was in business in New York from 1881 to 1890. He was an importer. Bb high pitch was common both here and in Europe.

The corks acted as bumpers for the finger bottons, just as felts would today.

Except they aren't where felts are placed; they're almost like packing around the stem of a gate valve.

Yup, but they're not doing the sealing. I've got valves like that on my Henry Distin Eb tuba.
