This guy has a bunch of interesting stuff. I wish i could only read his site :)

You can read the site using the Excite web page translator.

I believe that Master Pyraminx as per german patent has never been produced, but may be that very same Master Pyraminx on the japanese site, as I don't really know what internal design it has. There is only handful of Master Pyraminxes with serious collectioners in Russia, as there was an attempt to produce these once back in Soviet Union times. The attempt was unsuccessful due to structural weakness, and the whole run of the puzzles had been destroyed, but may be justy a few that got into hands of collectioners. That russian Master Pyraminx had been produced per russian patent. Please see a reference to the patent on this forum not so long ago.

So, right now I don't think there is a way to obtain a Master Pyraminx. Unless someone designs and produces is from scratch.

I contacted the person who runs the website listed further up in this thread, concerning the master pyraminx, and he says that he has no more stock, but that he may make some within a year or two.

-Hope this helps
