first I would say it is French.
second I am going to guess it was built by Marcel Leyat in the early 1900's
The "helicron" series of propellor powered vehicles had their roots in aviation and the builders really thought this was the future of automotive propulsion.
I assume the single rear wheel is what steers the vehicle, another holdover from aviation.
"It works fine for an airplane!"
Fine for taxi-ing but once you go faster, the plane is off the ground, a car is not. It took quite a while to ditch this "rear steering" element as even 4-wheelers were built like this.
I think only the earliest models of these things had rear "pusher" props.
that's all I got.
