1919 Cotta Truck-Tractor Transmissions Promotional Ad #1944

This original 11 x 14" magazine ad was published in 1919 to showcase the fact that many trucks, tractors and WWI vehicles use Cotta Synchronized clutches to avoid having to double clutch to avoid gear clashing.  The company was located in Rockford, IL and the ad shows a nice illustration of the clutch working design.
