Triumphonic Flugelhorn #4

This Triumphonic Flugelhorn has a unique wrap to the design. Instead of the usual flugelhorn tuning slide in the leadpipe, it has a tuning slide in the bow. Serial number is 20xxx.

I have seen reference to this wrap and design on various historical websites, so it is known, but not very common. I am curious as to why the design did not take off. The instrument plays very well.

This instrument has extensive engraving on the bell.

Records show this instrument to have been manufactured on 22nd December 1927.

This instrument is unrestored.
