Solved: Wendax 699 - Puch 500

[grobmotorix]

My next guess would be a Perl...

[Wendax]

Not Perl.

There are not many possible companies left. 

[João]

Avis?

[Wendax]

No

[grobmotorix]

The radiator details look a little bit like Puch...

The radiator details look a little bit like Puch...

Yes! To obtain the point, please tell (and prove) me which model this is.
Locked for you.
Here are the pictures I have:

It´s a sweet little car, but I have no access to my books and no clue really.

The year should be something between 1928 and 1932, but I can´t give you any details.

Please unlock it again and let the others guess again.

[Wendax]

Okay, unlocked and open for all again.

According to Georgano they stopped producing cars in 1925.

[Wendax]

After a look in the right book (thanks to the central public library in Hamburg  ) I know that Georgano is wrong. It was made within the timespan grobmotorix suggested. It was a Puch production model, but only very few were made.

yeah, a Puch book is waiting for me at one of the libraries in Vienna, but as my whole family is sick, I will not be able to look at it until next week. By that time someone else will probably solve this

[Wendax]

This puzzle has been around for quite a while, so perhaps it will stay for another while. Just care for your family.

I think this is one of the few Puch 500 small cars which were built in 1928 (model year 1929). It featured a 510 cc motorcycle engine, capable of 16 hp.  Only 12 units were built

[Wendax]

I see that we read the same books. 
Right you are, one point is on the way.

[Wendax]

Another one where I didn't store the pictures. Can anybody help?

[Wendax]

Puzzle picture restored. Thank you, Pal!

[pnegyesi]

a combination of perseverance and the right date yielded the necessary results. Untouched original picture is now restored.
