Kanstul 1670: What is This Thing?

I get the TIS for the open horn, but why the odd mechanism for tuning the valve section?

Otherwise, what do people think about this model?

There is no bracing whatsoever -- they probably put that there so you don't bork it by pulling at an angle other than 0⁰. Without the F attachment cross brace to push off of, any pulling on that slide will likely put torsion through the horn.

That's exactly what it is. Tuba players often have something like that installed on their first valve slides.

I presume it lets you pull to E without guessing. The old Kanstul website advertises the model as as having a "Fast E Pull".

Trumpet 3rd valve slides have the same thing.

That's not correct. The thin cross brace is part of the tuning slide. The 1670 that I own had the E pull stop removed by the person I bought it from. I haven't really missed the stop. Here's a photo of a different 1670 with the stop removed (copied from Brass Exchange archives).

I can understand why someone would remove it. I've had the pleasure of sitting next to someone playing a 1670 with a loose stop rod screw. I don't see how the rattle/buzz on certain notes didn't drive them insane.
I've seen trumpets with that sort of device on their main tuning slide; they were advertised as being playable in Bb or A (this seems to have been something of a fad in the 1920's and 1930's).
Closer to home, the optional Eb-D extension for the Olds P-24G had a stop rod on it.
