A used Trico CHM 11-8 Windshield Wiper Motor that I got at an auction of vintage car parts.

This is stamped "Ford" in script inside an oval.

For use on 1951 Ford cars except station wagons.  

I rocked the lever back and forth and this produces a puff of air when I do.  The rubber cushions at the mounting holes have worn off.
