I think this is the Rolleiflex I have, based on its serial number. Of course it's not 1892; the serial places it sometime in the 1960s, probably.
This catalog page extols the virtues of a "Zeiss-Anastigmat" Lens; it's kind of a yawner of a read!
I love my Rollei, but I admit I haven't taken many pictures with it; I traded up an even older camera for it, and I used that one quite a lot. This is the camera you want to use to take a self-portrait with!
