I don't think Billy's Dad was ever mentioned as a toy collector by him but I know you spoke to him more than most Del (when he was respected), his cousin was (or was it brother in law?) Rik (or Rick), he also said Ruth (or Ru) collected as well and that they both used HIS account to buy and sell but didn't use his money..lol
I know for a fact Bill had genuine stuff pass through his hands and his knowledge was second to none but when he went bad all of the credibility and respect went with him, UK/Euro Star Wars items took a real knock as a result because he was ahead of the game as far as variations and things were concerned so we basically had to start over again as no one knew if he was telling the truth, faking things etc. What is most upsetting as a bystander to all this is that not only did he do a number on a lot of people, ALL of the money he is making from these sales should be going to people who he ****ed over years ago but it isn't..it's probably buying him new bunny suits and cameras.
If you check his feedback you can see he bought the Palitoy ESB Shelf Talker for £10 on ebay and sold it for £145 or so..no question the thing was real but that is £135 profit into his pocket instead of into the hands of the people who have left the hobby because of his scams. I don't care if it is his Dad, Mum, Sister, Wife etc - the guy is alive and well and if he wasn't to blame for what happened there would be no reason why this wasn't resolved years ago. All I can see is a big fat bunny getting richer (and fatter)!
