Here's the Mecum marketing link to the Gregg Ziegler 144.9 mph 1960 Daytona Speed Weeks, when this car was being auctioned a few years ago. You'll see a photo of the 150 mph speedo. This low-mile all-original unmolested beauty, that I saw a couple times in person, clearly sets the mark that the 150 Mph speedo was the factory issue for the 4-speed Pont-a-Moussin Fs.
In January 2013, while in AZ for the auctions, I took several photos of the black Don Petty convertible, along with his notebook - the notebook had several handwritten notes and small photos of this car, but nowhere mentioned whether the "200" was a Kmh vs. Mph speedo. It did have the "200" speedo installed at that time. If Kmh, this would translate into roughly a 200 Mph speedo, which would not have been equivalent to the 300-Fs' 150 Mph speedos.

On another list I am on (for early A bodies), the subject of the 300F with the French 4-speed came up. Here is a shared link from that list:
Notice the photograph of the 200 MPH speedometer. Does anyone know if the export speedo for kilometers, looks the same? I’m thinking it is, and they recalibrated it for MPH instead of KPH, but would like to hear from anyone in the know. This was the first I heard of the 200 MPH speedo in the F Specials, notice it doesn’t state MPH or KPH.
