Solved: Allemano's № 809 - Walter ADV 150 HP truck

[Wendax]

ADU 150 HP?

It has double wheels at the back, so I'll try ADG 150 HP, as that's the only letter left in the code listing I found.

I found a similar AGV, so I'll try ADV 150 HP.

Very good - a Walter ADV it is. The brochure shown dates from 1939. Strictly speaking, the "150 HP" is not actually part of the Walter model designation, it simply advertises in the brochure that this truck has a 150-horsepower engine (quite powerful for the time). Good work by Wendax, and another fun quiz.
