An article about the World War I-era American Protective League civilian Justice Department auxiliary in the 22 July issue of the
New York Review of Books includes an image of a primitive-looking truck (Image 1, below).
My initial impression was that it was a Jeffrey/Nash Quad (Image 2) or an F.W.D. Model B (Image 3). But further examination of images of WWI U.S. trucks convinces me that it was a Mack Type Two (Images 4 and 5). To me, the giveaway is the prominent Mack Type Two dashboard, not present on the Jeffrey and F.W.D. vehicles (Image 6).
Although the Mack Bulldog AC with its distinctive engine cover was the most widely-used Mack truck overseas in World War I, a lot of the old Type Twos (as well as the ABs with conventional hoods) remained in service on the home front.
Can anyone with more expertise on U.S. WWI-era trucks than I have confirm or correct this identification?
