I do have one of these. It's unused and the brass/blue frame. It's similar to the picture here:

It's unused because it was a prize I won in France last year and because I didn't have a slot for it, left it with a friend over there. If you're interested, I can have it shipped to a dealer of your choice. I'd be looking for £100 + the postage
