Colmor "Light Up" Dexterity Puzzle, c 1930s

This is one of three Colmor dexterity puzzles I'm listing, all from the 1930s or so, and the graphics of which I just love, looking very classic Dick Tracy-esque to me. In this one the task is to roll the four silver balls in the cutouts on the headlights, which takes quite a bit of finesse, especially as the car itself sits atop the backdrop, floating around as one tries to the land the balls! 

5" x 3 1/2" x 1/2" and in great vintage condition.
