I just bought a pair of these on eBay; a closer look shows only one screw at the top, not two.
A quick online check reveals that these were made for the earlier, AC-powered 'vibrator' cars (boxes are dated '1960').
Will these work on DC with the T-Jet 'pancake' motors, and, if so, how are they to be wired?
Thanks!
