I just recently put this badge on the radiator of my A:
It is an original rally plaque (one of an estimated 500 made) given to the participants who drove their cars to the celebration of the grand opening of the Ford factory in Koln, Germany, 12-14 June 1931.
The motifs on this badge include the Ford factory in Koln, the Kolner Dom (Cologne Cathedral) and the bridge over the Rhein River in Koln. There are two variations of this badge with the main difference being the name of the manufacturer, a slight difference in font size and also a very slight overall size difference.
Fordially,
