I was talking with someone about Dixi and came across Helmut Kazimirowicz’s excellent German web archive http://www.dixi-automobile.de
The images are particularly evocative. Kazimirowicz states “This photo was taken in 1935 at the Berlin Motor Show. The persons shown there are marked on the back. The car on display is a Willys Overland Crossley Austin Nippy, produced in Berlin since 1933, as the Austin Seven license had already expired with BMW in Eisenach. Mr. Adam, far right, was the owner of the factory in Berlin”. Spend some time scrutinising his excellent site.
