There's an Ondioline on Ebay France !
I have never seen a decent photo of one of these before, so to see one for sale is a real treat.
With 6 days to go the bidding is already up to £103 - I suspect this will climb a lot higher.
Incidentally this one appears to be different to the one pictured on clavioline.com. It seems to be lacking the switches on the keyboard unit.
If that wasn't unusual enough there is also a rare 7" EP of Ondioline music from the 1960s. Apparently this record went for $405 the last time it was auctioned !
Update: The Ondioline sold for £583 (851 Euros), the EP didn't sell and has been relisted.
