Meitner Museatex AT-2 turntable

I'm fascinated by the Meitner AT-2 turntable and the concept of platterless design. Does anyone know about these turntables. I can't find much info, nor can I find a used one. Do people hold onto these forever, or were there just not many ever made?

Thanks in advance for any info you might offer.

Merry, Happy, Peace on earth.
