I am working on an article for Supply Line about Zenith carburetors and need some background information. Zenith started out in Lyon France before WW1 and opened a US office in 1911. My questions are: How much effect did WW1 combat have on Lyon and by extension Zenith production? I have some books on WW1 but not anything useful. I don't think Lyon was shelled or bombed but would like to study it more. Secondly, does anyone have a photo of a Zenith carb on a WW1 FT tank that can be published. I had a lot of FT stuff but don't anymore. Lastly Zenith didn't go "big time" in the US til they got the Model A contract from Ford but can anyone verify if everything ship from France for assembly during WW1 or were Zenith castings done here in the Dodge building? I have contacts at Zenith but Tanknet is mighty and I am curious as to what the forum may know...
