Yes, it was used for long-distance rallyes like the Alpenfahrt. I don't want to torture you anymore. I was looking for the "Geländesport" designation. Six W22 Geländesport were built: three in 1933 and three in 1934. They only differ slightly. In fact, the one Otto posted is the 1933 version with doorhandles and a grill with less bars than the 1934 version from the puzzle picture. I found it quite amazing to find a rallye car as staffage for a romantic postcard. Can you imagine something like that with, let's say, a Metro 6R4 or an Audi Sport quattro S1?
One more point for you.
