Actually , as one would guess, they are very common over here but due to the mix of quality of these horns they tend to be avoided by most. The Keilwerth stencils are pretty good but, since the " real" thing is rather plentiful too, why would anyone bother to buy a Schenkelaars unless it is very cheap? In any case the baritones seem to have a better than most record. A few days ago a Dutch sax collector was telling me that they at Schenkelaars also bought from Gubana of Timisoara Rumania. He was very derogative about these horns. I have actually seen some very beautiful art deco Gubanal ( cannot vouch for their sound because I haven't played any) heavily silver plated which looked absolutely stunning but my guess is that this was not the case with this other particular stencil........Go carefully - there's probably a good reason why they are rare, no-body bought them!
