Just wondered if anyone could tell me any suppliers/retailers of the "gimmicks" often seen on exhibition layouts. I've searched several model rail magazines and done loads of google searches. I've found suppliers for the flashing weld/arc lights, etc., but can't find the more obscure/expensive ones that have a motorised part as well as the flashing led, such as the opening portaloo-door with a man sat inside - there are others too that I seem to have seen on more than one layout but never can find in the retailers. Can anyone point me to where these are sold?
