The original owner thought this was purchased sometime in the 1950s not sure.
Condition is great for the age of the toy, both cars look good, the spring is a little weak but still winds up and moves some.
The hook that connects the two cars needs some work to make them hook together.
It does have 1- key , 2- cars , the box is in rough condition and may be missing some pieces.
Any questions please ask.
Thanks for looking.
