The Dolnet Stencils
(Bel Air Stencils)
These are one of the few stencils I've ever seen that actually have MORE features than the horn they were stencilled from.
There are at least two models of these horns: "The Royal Jazz Model", which sometimes has additional keywork (altissimo D# trill, G# trill, etc.), rolled tone holes and a microtuner neck, a la Conn and one sometimes labeled "Artist Model" that generally doesn't have all the additional stuff, but is striking, nonetheless.
As mentioned in the introduction, these models sometimes have been done in Sparkle Lacquer, like some Buffet Superdynactions. I've now seen two of these models, so I doubt that these horns were relacquers.
