Thanks. But, I think you can count on one finger the number of potential customer for the VDCH. Me. But, I am too cheap to pay full price.
It turns out there are several models of the VDCH. The heights vary between models, but, the sides are consistent at 24". I decided to go with the "prewar" model for my deconstruction efforts.
Discovered the reason/logic behind the shape of the horn and the reflector; Voigt did something really clever. The two curves for the reflector are also tractrix. But, they are "flipped". The "mouths" of these curves point toward the sound source, the "throats" toward the room/listener. I do not know of any other such horn arrangement.
The horn itself is a quarter of a full tractrix horn.
Interesting stuff.
