Just going by the configuration I would guess it is a model of a Tartra I have never seen before, 3 headlights was not unusual for that maker (well before Tucker used that feature) it looks like it is a rear engine air cooled model, that would fit with the V8's they used. Proportions are about right. The only thing that throws my idea into question is the Right Hand Drive. Below is a Tatra 87 from the mid 1930's
A wild guess on my part - maybe some Tatra prototype that never came to be? Car looks too polished to be home-built, and definitely has some Tatra styling cues.
The U.S. government could get away with right hand drive, and did on postal vehicles that drove on the right side of the road and let the carrier reach out to the mailboxes that were on the side of the road. Without getting out of the vehicle. Now why didn't someone point out that the images of the car may have been flipped by computer magic and the car is really left hand drive!
If it was actually a reverse image, you wouldn't have been able to read the lettering as 'U.S. MAIL'.
And yet you post a photo of the Jeep, and not the 'unknown car'........ ????? I'm so confused........
The photo just came along for the ride when I quoted the other person's post. Happens all the time on this forum making it a requirement to follow a post of quotes back to its origin to make sense of the latest quote. (the third left brings you back to the starting place and if you continue past then you have made a right.)
I have never seen one of these pulling a trailer before! Must be going downwind! I have also never seen one in large open waters
