Marx used to make a vast number of playsets.  Often the figures were 45mm or 54mm or even 60mm.

Still the accessories were often much smaller.  Is this a tool box, or a building?

I think it's a building about 1/300 scale.

This siren is mounted on the roof of a building with a tiny door at the bottom, maybe 12mm scale.

Here we have an observatory, also about 1/300 scale judging by the doors.
