1929 Diamond T Model T4D 1.5-Ton Tanker

Offered by Mecum | Indianapolis, Indiana | May 13, 2022

Diamond T built some beautiful trucks in the 1930s and ’40s. But the company was actually founded by C.A. Tilt in 1905, back when things were more… functional. This is the earliest Diamond T we’ve featured.

At the end of the 1920s, trucks were big, heavy, slow, and purposeful. Styling hadn’t entered the arena yet. This tanker truck is powered by a Hercules 4.1-liter inline-four paired with a four-speed transmission. In thinking about why this truck survived scrap drives during WWII, I’d guess it was used as a water truck on a farm or something where it was relied upon.

This truck was part of the Hays Antique Truck Museum, which Mecum liquidated earlier this year. So why is it back at auction (and with the same pics)? Either it didn’t sell, it got pulled from the catalog at the last second, or the winning bidder flaked. In any event, glad it’s back so we could feature it this time around.
