I think it may be Dave Saunders who goes around claiming to have worked on many of the shows and owns many of the original models.....even though they all look like kits he's made.
I saw part of a talk he did at a convention around 12 years ago, where he passed himself off as an SFX model maker. Claims he build SID for UFO but he must have been about 5-years-old at the time. Then he worked on UFO, Space 1999 and went on to build many of the models for Star Wars, like the Millienium Falcon, 8-foot Star Destroyer, etc, talked about how they were filmed at Pinewood but unfortunately all destroyed during the process!! He obviously had never heard of ILM and that everything model wise was done in the States!!!!
He spoke for an hour and got most of his facts wrong but the audience didn't seem to notice, although one person mentioned that they had seen the original Star Wars models in a touring exhibition so he changed his story to say that George Lucas kept a couple of models for publicity purposes. One of the weirdest convention experiences I've ever had.
PS. they don't look exactly like the originals because he's restored them..... well that was his excuse at the time.
Yeah think that was the guy,most from fibreglass/resin kits back in the day,choco stingray,toby chamberlain terror fish,big tb3 the same as i recently sold,tb2 pete hutton,plus Some smaller resin kits...warp etc,not sure who did the tb4,everytime i asked about a model he said they were original props so i told him the origin and he kept changing the story,a bit odd really.
