I just recently acquired a Rather well used 1938 Roleiflex Automat1, with Tessar 3.5 lens, took the first roll for developing and kept my fingers crossed. Apart from a couple of shots (my fault, didn't check the light metre) they came out very well indeed, information and contrast is brilliant, although there are a few tiny cleaning marks on the lens they don't show up at all on the prints (which are much better than the download). All I want now is a lens hood, for those odd sunny days.
All in all I'm well pleased.
One photo here from the first roll.
