DIAMOND T 1905 – 1967 Chicago USA

The Diamond T was an American automobile manufactured in Chicago from 1905 until 1911 by the Diamond T Motor Car Company. It was a powerful touring car (models up to 70 hp were available). The company later became known for its trucks. By 1967, as a subsidiary of White Motor Company, it was merged with Reo Motor Company to become Diamond Reo Trucks, Inc.

During World War II, Diamond T produced a classic heavy truck in the 980/981, a prime mover which was quickly acquired by the British Purchasing Commission for duty as a tank transportertractor. Coupled with a Rogers trailer, the truck gave sterling service with the British Army in North Africa Campaign, where its power and rugged construction allowed the rescue of damaged tanks in the most demanding of conditions. In addition Diamond T built the entire range of the G509 series 4 ton 6X6s, including cargo, dump, semi tractor, and wrecker trucks, as well as some lighter trucks, and even G7102 half tracks. Diamond T ranked 47th among United States corporations in the value of World War II military production contracts.

Diamond T manufactured two pickup trucks: the Model 80 and the Model 201. Both pickups were powered by the Hercules QX-series 6-cylinder engines. The Model 201 was produced from 1938 to 1949.

Author: Jeroen

In Dutch, my homelanguage: Ik ben Jeroen, tot januari 2015 was ik al dik 26 jaar werkzaam in een psychiatrisch ziekenhuis in een stad vlakbij Werelds grootste havenstad Rotterdam. Eerst als verpleegkundige/begeleider op high care, later op afdeling dubbeldiagnose (verslavingen) en ook nog een tijdje als administratief medewerker. Ik heb een spierziekte "Poli Myositis" (alle spieren zijn ontstoken) daardoor weinig energie. Sinds augustus 2015 is daarbij de diagnose Kanker gesteld, en ben ik helemaal arbeidsongeschikt geworden en zit middenin de behandelfase. Gelukkig ben ik daarnaast getrouwd, vader, en opa, en heb de nodige hobby's. Een daarvan is transportmiddelen verzamelen en daarmee een blog schrijven. Dit blog begon met bussen, maar nu komen ook sleepboten, auto's trucks en dergelijke aan bod. Kijk en geniet met me mee, reageer, en vul gerust aan. Fouten zal ik ook graag verbeteren. In English: I'm Jeroen, till januari 2015 I was already 26 years working as a nurse in a psychiatric hospital, near Rotterdam, Worlds biggest harbour with more than 98 nationalities living within it's borders. First I worked on closed high care ward and the last years on a ward with mainly addicted people. I liked my work very much. In 2007 I got ill. I got the diagnose Poli Myositis, a musscle dissease. Al my mussles are inflamed. And last august I got another diagnose. Cancer. It's plaveicelcel carcinoma and treated with Chemo and radioation. So I've even less energy than the last years. Still I try to make something of my life and the blog is helping with surviving with some pleasure.

  1. To those who love Diamond T trucks.

    My brother won this truck in a raffle in the mid 1980’s and he brought it home from Hershey PA. We were told it had placed in a national show, was a cover truck of the “1985 Workhorses of Yesteryear calendar” and then donated for a raffle to help fund a automotive museum/library. The truck has been stored in a heated garage since the 80’s up to my brothers death last year. It was then transported to the auctioneers in February this year.

    This is copied from the Auctioneer’s website listed below:

    My family would love to see it go to someone who would appreciate it as much as my brother did.


  2. Great post however I was wanting to know if you could write a
    litte more on this subject? I’d be very thankful if you could elaborate
    a little bit further. Appreciate it!


  3. Write more, thats all I have to say. Literally, it seems as though you relied on the video
    to make your point. You definitely know what youre talking about, why throw away your intelligence on just posting videos to your blog when you could be giving
    us something enlightening to read?


  4. Thanks for one’s marvelous posting! I quite enjoyed reading
    it, you can be a great author.I will make certain to bookmark your blog and will come back from
    now on. I want to encourage continue your great job, have a nice holiday weekend!


  5. Regarding the photo above, #8 from the top: Can anyone tell me anything about that truck and its unusual front wheels? What was it used for? I have a similar photo but it seems I can’t upload it here.
