Lights were not asked for but built in anyways.
The original studio models as i found out during my reasearch before building were smaller than this so trying
to use any kit parts or using the toy tracks and wheels were out so thay had to be scratch built.
The track is just one long rubber band, cast from a rigid mould using RTV rubber
with some aniline black powder (nasty stuff but effective) to get that grey colour.
The exterior detail like the vents and stuff were cast seperately and glued on.
