Strong Truck Sales Even During the 1930’s

During the 1930’s Diamond T was selling more trucks than both White Motor Company and Mack. Diamond T was fifth behind the big three automakers and International. Many manufacturers experienced very difficult times during the Great Depression years but Diamond T actually had record sales of over 4,100 trucks during the 1933 model year. The company was very well known for their quality medium and heavy-duty trucks. It’s been said that Diamond T actually outsold many rivals because their trucks looked better. In other words, Diamond T successfully integrated heavy truck design with style.

Two things many truck enthusiasts point to about the Diamond T truck design are the distinctive grille bars and the top open

ing side hood panels secured by plated clamps. Design changes at Diamond T really began during the 1920’s when trucks were not known for their styling. In fact, trucks were known for anything but smart styling until Diamond T started redesigning. Diamond T was really the leader in changing the appearance of medium and heavy-duty vehicles and probably the best example of their restyling came out in 1933.

A Big Military Supplier

Diamond T’s reputation was as a builder of heavier trucks, typically one ton and larger. The company built what most considered quality heavy trucks with style. During the First World War Diamond T built more than 1,500 Liberty Trucks for the military. During World War Two, when the company produced over 50,000 vehicles, many of these vehicles were purchased by the British Purchasing Commission. This included half-tracks, army wreckers, tank tractors, and tank movers.

The White Motor Company purchased Diamond T in 1958. In 1960 White moved all production from Chicago to Reo’s manufacturing facilities in Lansing, Michigan. The Lansing Division of White Motor Company then produced both Diamond T and Reo trucks. Starting in 1967 the two trucks became one. No longer were two separate brands being built. This move created White’s new Diamond Reo Division in 1967 and they began producing Diamond Reo trucks.

The 1937 Diamond T’s had bow fronted grills along with new and broad fenders. The windshield was at a 30-degree angle. The dash panel with its large diameter “airplane type” instruments was largely from the 1935 model. Another feature with the 1937 Diamond T Pickup was an electric clock on the dash. You would not have found that on another truck brand in 1937. Also on the dash was a cigarette lighter.
