Of course I don´t have player pianos in mind, but just movements being fed with strips, made by using MBC.
Googleing tells me, Nidec Sankyo -
http://www.nidec-sankyo.co.jp - were producing 33-note (fully chromatic), 30-note (semi-chromatic) paperstrip-movements for relatively short periods in the nineties, and still make 20-note (diatonic) ones today.
Their strip-feeding mechanism seems to work with paper of various thicknesses.
The 20-note sankyo is offered today by
http://www.spieluhr.de at a price of 35,22 EUR, as well as by
http://www.leturlutain.fr at a price of 60 EUR, who also offer a 33-note sankyo movement at a price of 370 EUR - wondering, where they got them from: still in store for 20 years because of the price?
For sankyo movements I didn´t find any more source until now, do you have one to add?
Edit: Seems, I missed the 33-note music-box (sankyo movement built in a wooden box) offered by
http://www.spieluhr.de at a price of 428,40 EUR. Sorry for that!
