Whilst I don't know that much about Bond "casino" film props, there are many that do and like to share their knowledge so I've picked up the odd titbit here and there. I know quite a lot about the Dr No/Le Cercle ones but it took a lot of research and there is still much I'd like to know (like the serial numbers of the ones sent to the studio and any seen onscreen) but doubt I'll ever find out.
There are many different types of fake ones out there so would not be comfortable buying any unless a Thatched Barn turned up, (another that was from an actual casino but also used in a Bond movie) but as far as we know, there is just the one found so far and that is going nowhere.
Thanks though, Bob.
