mark c has one on his floor. go and have a look at his Lost in Space. Saw one sell on ebay recently for $3,300. not a well known pin but it was only a small production run and i love segas to death. If ya ever want to sell it for a reasonable price, pls keep my details.
i actually recieved a full playfield set of toys by accident for a Lost in Space pin when a seller in the USA sent me a full set of toys for a spare starship troopers. I said "what the hell are these" and threw them in the bin. Only recently when i relooked at the Lost in Space playfield did i realise the big mistake i made
(although you can find the toys individually 2nd hand from toy sellers in the USA cause they were generic toys added to the pin).
Anyway, post some photos if u can, and others who have a Lost in Space can spot some differences perhaps.
