Solved -PJ568- Lorenzo Gradé's 6 cilindros 7hp from 1927

[Paul Jaray]

I'll try again with this kind of puzzle.
Slight change of rule:
I won't reveal the nationality but I can answer to generic questions about that.
It should be easy for one aspect but harder for another...let's see if you are lucky and quick!
(I'll change the rule if it will take too much.)

The bystanders look french - is the car french?

[Paul Jaray]

I can't reveal the precise nation but only generic questions about.
Anyway it's not French.

Central European region? (one of the Warsaw pact countries)

[Paul Jaray]

Not there (but not far  )

Before I go any further, I have to clear this nagging thought: is this an Alba?

[João]

Cyclecar Loryc from Spain?

There´s a similar Soriano-Pedroso...but it´s French.

Sanchis?

Perhaps I am mad, but is what I see through the shop glass an advert of a Chevrolet about 1925-6?

[grobmotorix]

I don´t think there is a connection to Chevrolet.

Elizalde?

So we have a spanish car, pictured in front af a Oakland dealer who has no connection with the car!
The car seems to have a 6 cyclinder engine; does it comes from a well known maker or is it produced by the one we are searching for?

[Paul Jaray]

Elizalde?

Nope...

It is a six and produced by the one we are looking for.
Locked for your next guess.

[Arunas]

Was it made by a company or more like an individual project?

[Paul Jaray]

It's still locked for targhediferro.

It took me three hours of digging and improving my poor Spanish, but finally I found it.   It is the 6 cylinders car built in 1927 in Zaragoza by a man named Lorenzo Grade'. The engine was almost 1100 cc.
