You can find an overview video of one here. A small handful of these have come up on the site here.
Some pics of one via this auction
Not this is not the one in the video above. According to the listing: "Turns on, but about half the keys don't work or have a lot of static noise. There is a constant hum from the output. The flute buttons for the Bass Organ Acc. section are sticky, and there is something rattling around inside when moving the keyboard. This is a Polish keyboard and uses a 220 volt power cord/adapter, NOT included. Comes in a hard case. Due to it's age and condition, this is being sold 'as is'."
