Diamond T identity help

Recommended Posts

New here, but have a mission and am asking for help! I have a set of photographs taken in the months leading up to the testing of the first atomic bomb. They show a crane truck, but frustratingly only from rear angles. I'm only guessing the crane is mounted upon a Diamond T truck but need input from those who might be more familiar with the type. If it IS a Diamond T, anyone know anything about the model?

Not a Brockway 666, wrong shape of front fender and smaller tyres.

It looks like it could be a lwb 4 ton Diamond T with a half cab.

According to Bart Vanderveen's original bible of WW2 vehicles, the Canadian army acquired more than 1100 special long wheelbase (201 ins.) model 975 chassis/cabs for mounting revolving cranes and other special bodies on. I can see 'USA' painted on the crane cab, but in Bart's book there are no Diamond T cranes listed under US vehicles. I would say the one in the photo is a 975.

Thanks for the input! It was the fender and grillwork above it that made me think Diamond T. Even though there is "USA" on the crane cab, there are no other markings and I don't think this vehicle is in US military service. A Coleman G-55 crane truck was also in use at the test site, and that particular vehicle, in Army service, carried a full compliment of stars. I think Richards posting might be the case as to what the type is. I believe it was owned by the Eichleay Engineering group of Pittsburgh who had been contracted to do some heavy equipment movement at the test site as Eichleay had a reputation for moving oversized items (penstocks for the recently built Hoover Dam is an example) and collected equipment acquired to perform such jobs.

Thanks all!
