Yes, it's Richard's GX (not sure it's worth that much but what do I know?). It used to belong to Mickie Most and was part of RAK Studios back in the day. When Mickie died in 2003, his studio was liquidated and I tracked this GX down for a collector in Germany who wanted to add one to his collection of organs.
Ultimately, that bloke got cold feet and backed out (UKP 25,000 was too steep a price, and he "would rather buy ten other organs instead").
He still owes me an Oberheim Four Voice -- he bet I would not be able to source and track down a GX-1 for him. He lost.
