Roland WS-1 Programmer for CR-78 Rhythm machine

Hello, …

I have a WS-1 progamming unit for the Roland CR-78 drum machine, which is supposed to be the first Rhythm machine ever, on my studio shelf and might only get lost under a pile of other gear. Is there anybody ( or does anybody now somebody ) who wants to own that rare little gadget? Usually, you find it only in museums, these days.
Please, PM me for details…

Cheers, …
