What era of pinball are you after? Space/Rocket themed pins have been around since the 1950s.

Lots of cool games from the 1950/60/70 era with that theme

Does your Skylab work as it should?

Just a word of warning though - you get another pin and they will breed like rabbits 

lol

The earlier the better!!

Anyone got any leads??

My skylab is behaving well, the spacelab special scoring isn't working right though. Waiting for the manual/schematics to investigate further. Also a few so-so globe sockets but all will be addressed in time. Just had a flipper rebuild kit arrive too.
