I’ve posted something similar to this video, but not this specific one (at least that I can find). This early 1941 film reel is narrated and shares the news that Ford’s Reconnissance Cars would be joining the Army. The video is located at the National Archives.

Interesting that the test cars had canvas half doors and used chains on the tires. 45HP Ford tractor engine with speeds of 55-60MPH stated seems a stretch. Lots of “bounce” in the ride for Mr Edsel in the back. The swivel headlight idea was a very practical addition. Overall pretty effective for intended use.
I believe the government’s requirement for a 4 cylinder engine forced Ford to use a tractor engine because that’s all they had. Willys ultimately was awarded the jeep contract because they had the better “go devil” engine.
Cool video.
I wonder when Willy’s got the contract how many every day they were making?
The FORD tractor engine was half of their famous V8 , if they really wanted more HP I think they could have done it .
