 | | Can someone identify this 'instruction kit' - red flip top hard case
|
|
I ended up with this 'red container' with a flip top from a collector we bought out, but have been unable to identify it's kit number or where it would have originally come from. Inside the red flip top case is a series of instructions for various (...) (20 years ago, 6-May-04, to lugnet.technic)

(...) So what happens if one set of legs manages to lock, but doesn't want to unlock, while the other set of legs never locks at all? It's possible that the front/back leg pairs will behave differently if the back legs are longer like on a real (...) (20 years ago, 6-May-04, to lugnet.technic)
