And now I have one

Hi,
 

 I already owned 2-operator FM synth (PSS480), several 4-op FM synths (FB01, V50, Orla DSE24), and a classic DX7 sound 6-op FM synth (TX7). And now I am the really proud owner of an 8-operator FM synth. And no, it's not the FS1R. It's a rare and almost impossible to find FVX-1 rackmodule that now is mine. 

 

 Does anyone have any idea how many of these were produced and how few still exist on this globe?
 You probably have never seen one, maybe you have only heard of it. There is some but not much info on the internet here:
