In a spotless service bay at A.W. Carter’s Hudson dealership, we find a technician demonstrating the workings of a state-of-the-art King Motor and Ignition Tester to a car owner on April 6, 1936 in a posed publicity shot. We found an ad in the December, 1935 issue of the Automobile Trade Journal (below) that describes all of the test functions that the machine can perform. The results promised by such attentions on the big billboard in our photo were good reasons to “Bring Your Car to Carter’s.” You’ll find many more Hudson related posts on The Old Motor.
