The Plateau System Clarinet

I just finished overhauling this late 1920's/early 30's French stencil plateau Boehm system clarinet and am wondering - why don't we see more of these? For folks who aren't familiar with the design, it has covered keys with pads like a saxophone, rather than open rings like a regular clarinet!

 They sound great, are easy to play, are a real help for people with small hands, thin fingers, arthritis, diabetic neuropathy, and hand injuries. I've overhauled both Boehm and Albert system versions and both sounded great! They are a bit harder to work on, I admit, and I'm sure that manufacturing costs are a higher, but what a wonderful option to have available! I know there would be a demand as I receive requests on a regular basis. Does anyone know if they are still being produced by a major company in wood, ebonite or metal? Can they be special ordered? Why are they so rare? Feel free to comment....
