A May 1939 article shown below from Boy’s Life adds to the evidence that the use of the term Jeep existed prior to the introduction of the Bantam BRC in September of 1940.
By November 1940, the term “jeep” was being applied to the Bantam jeep (and/or the Willys Quad, delivered in mid-November), according to court records, months before the delivery of the Ford “GP” model in March of 1941 ((the Ford Pygmy was delivered to Holabird near the end of November of 1940).
To me this opens up a question. Was the P=80″ wheel base a chance coincidence? Or was Ford cognizant that the new 4×4 vehicles were being called jeeps, so they purposefully took advantage of that to use the “P” to spell the onomatopoeia-initialism “gp” or “geepee” or “geep” as part of the delivery contract? I suppose Ford had a designation that O=70″ wheel base and Q=90″? If so, I’ve not personally seen those designations documented.
Now, modern articles call the Pygmy the “Pygmy GP-1” (or similar), giving it credit for being the first Ford GP. But, I have yet to see any documentation that Ford or anyone else was calling the Pygmy a “GP”.
In fact, two articles from 1940 indicate the new Ford recon car is called only a Pygmy and that more pygmies will be delivered in the future. See the middle and right column articles on this page (http://www.memorialmuseum.org/displaysmilitary-jeeps/item/ford-pygmy) (note that the 1969 article on the left hand side of the page does designate the vehicle GP-1, but again, that’s a much later article).
My guess is that the GP designation was more strategic than the innocent explanation of G=”Government” and P=80″ suggests. I’d welcome evidence showing the Pygmy was labeled a FORD GP from any kind of article or document from the late 1940s. (maybe this issue has been hashed out previously and I’m late to the party???)
In the meantime, here’s the Boy’s Life article (you can read it online).
