I bought back a 3-piece set for $1,200 and flipped it for $1,800 shortly thereafter; where the £1.000 was $1,000 and the £5.000 and £10.000 were $400 each.

Sorry, but that's the best I can do at this time... and, I am a buyer for a £1.000 should anyone have an example for sale.

Btw, no other pieces turned up in the US, since they made their original debut at an Atlantic City show many years ago.

David might be able to provide you with a more recent history.
