Can anyone tell me about the slide saxophone as used by Snub Mosley an instrument he designed himself?

"Mosley spent most of his career on trombone, but also invented an instrument called the slide saxophone, which had both the slide portion of a trombone and a saxophone mouthpiece. The instrument is prominently featured in his 1940 recording "The Man with the Funny Little Horn."

Apparently, this was the only time he recorded with his Trombaxaphone(?) lol

(Wikipedia)

"The peculiar slide saxophone was one of saxophonic curiosities that was a product of the early 20th century. Like so many of these quirky horns, the slide sax never caught on, and is now a rarity in vintage saxophone world.

The musician who is synonymous with the slide sax is Snub Mosley. Mosley was originally a slide trombone player, who also played the slide saxophone for decades.

There is only 1 known recording of Snub Mosley playing the slide sax. The song, “The Funny Little Horn”, appeared on the album, The Man With the Funny Little Horn. On that recording, Mosley plays the slide sax with a trombone mouthpiece, although in photos he poses with a saxophone mouthpiece on his horn.

There were only a few manufacturers of slide saxophones. Swanee and Reiffel & Husted are the 2 makes we see most commonly."

My uneducated guess - wait (lol) just heard the slide saxapone, so my educated guess is that this is not a viable instrument that contributed to jazz in any way. The sound is that of one of my percussive sound-effects (one of those kids' tubes with the ball in the middle that when you turn it it goes: Bloooooooop.

This song could have been played on his '78 tour, but I believe he only played it for the one song. (He passed in the early 80's per Wikipedia).

I do not believe this was a viable instrument that contributed to jazz, other than as a "quirky" conversational instrument. (To each his own taste, however).
