Neat pic. Looks like a 1919 car. It has the knurled, side mounted horn button. Interestingly, it has an oil tail lamp but no front oil lamps.
So how do you steer it? If you turned it more than a couple of degrees it would seem to just drive right out of its own track. Normally tracked vehicle steer with the brakes I think but this thing has a steering wheel and it does have what appears to be a "normal" front axle. Look at the huge disc shaped object on the rear wheel. I wonder if the steering mechanism applies brakes to the appropriate wheel at the rear to thus steer it.
Seen that one before but it is a real favorite. Would love to know the whole story of before and after. Wonder what became of that unit?
I find it interesting that they took the car's standard license plate, flipped it over and stenciled "U.S. ARMY ORD. DEPT." on it.
Looks like some HUGE brakes on the rear wheels? My guess would be operating them independently made the vehicle turn.
I'd love to see one of these cars in real life. I wonder if they ever built more than just the one in the photo, or if it even worked. Some slick engineering went into building that one if it did.
Same car, different view-
One of those officers in the back of pic #2 looks like IKE !!
