Columbia Two Speed: Company owned by Erret Lobban Cord (who also owned TWA-Transcontinental & Western Air, Lycoming, and ACD-Auburn/Cord/Duesenberg). AFAIK, first installed in 1935 Auburn 851's.
The only Ford products I've seen (vacuum controlled) Columbia two speeds installed in: 1941/48 Ford/Mercury Passenger Cars. I had a '47 Ford woody with one, a pal has several '46/48 Fords and Merc's w/Columbia's.
Maddux Inc., the CA Lincoln Distributor, founded TAT-Transcontinenental Air Transport in the 1920's, merged it with Western Air Express. The aircraft were Ford Tri-Motors initially.
Cord bought TWA when Maddux went bankrupt, then with his fortunes declining, sold it to Howard Hughes. Hughes later changed the name to Trans World Airlines.
