(Pete) There are at least four versions of these horns: Popular, Star, Highclass, and Regent.
From my current reading, there may also be a "de Luxe" and "Excelsior."
I have really no way of telling these horns apart: let's call the "Popular" the horn without a D# trill.
Here's one that has it.
Let's call the "Highclass" the horn that has the additional pearls.
Oops. This Popular model has them.

(Helen) According to research materials gathered by Uwe Ladwig, the Popular, Star, and Unser feinstes ("Our Finest") Modell, were available in the 1930s for an additional cost as "Super-Variante" (super variants).
