While at the Meadow Brook Hall Concours this year, I took a lot of pictures, but neglected to take a good record of the cars I photographed. I identified every single one from the catalog, except for two, which I am convinced were not even listed in the catalog. The two I couldn't identify fully was a white Huppmobile boattail racecar and a black 1928 Mercedes Benz Phaeton (problably a 630K). Does anyone know the exact/proper names for these two cars? See the photos of the Hupp (three of them, front, back, and engine) and of the Benz (just the side)
