As you know, I have 2 on the list (they are on ebay at the moment).
Always happy to deal privately especially as I can't sell abroad on ebay due to having no ID.
Good luck with your quest on the rest.
I'm managing to get hold of some of the old UK Playtime staff magazines hoping to find out more about some of the things we still don't know about for sure. RHMS Atlantis chips, Clermont Gold plaque and other such things but no luck so far. I've also been in touch with many ex-bunnies and other staff members but again, still no joy. I'll keep trying though.
I'm also hoping to find another 50p (without black inserts) that I have mentioned a couple of times, fingers crossed.
Hope life treats you well.
