A#437 Unsolved: unidentified propeller-driven three-wheeler shown at Brussels Salon in 1955

[Arunas]

I know only where and when this vehicle was shown. I suppose, little is known about this vehicle, in the main, so this puzzle is open for any discussions.

Any ideas what this could be?

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.

Interesting thoughts, indeed. However, according to my source, it is from the 1950s and makes me think it is not French

That's what I have too. If no information is available about this car, I'll award you a point soon.

Funny thing is, I have seen the front, but elas, without name.

Down to the hole?
