large european roadster identification

HAMBers,
since one can always experience the unlimited knowledge of the hamb collective, here's another hard one:
it was in the "readers help readers" section of a German cl***ic car magazine. the owner asks for help and I'd be curious to know what happens if the HAMB joins the quiz. And I'd be glad to help...
Given info:
- high quality making
- metal over wooden frame
- original color, green-blue
- originally maybe mounted on a Delage ch***is
- wheel base ca. 3,4m / 11,15ft

 

Grill reminds me of a Lancia.

Hey,

This looks like a pre war Audi to me, possibly a Type 225 from about 1937.


" Humpty Dumpty was pushed "

 

Horch. More precisely, the car that is owned by Judge Joe C***ini and won Pebble Beach a few years back. It is silver now.
