The 2-speed axle under the 30s and 40s Fords was the Columbia, not the Ruckstell.

A picture of the Ruckstell can be seen in this thread: Model T Ford Forum: Ruckstell or auxiliary transmission, opinions wanted.

The Columbia axle was available from 34 to 48 for new Fords. A picture of a Columbia can be seen here: Redirect Notice

 

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.

 

if i didn't live so far away i would take you up on that rear axle. that front axle is nice but i wouldn't have a use for it. plus i am half snowed in already all projects around hear stop when it snows. i have enjoyed this thread i know its early but merry christmas

 

Ruckstall's AFAIK, were only installed in Model T's.

 

Good Evening All! I realize that this thread is over two years old; however, I was curious if either of the two axles (Eaton 2 Speed and Front) are still available? Please adivse - thanks!
