As a 35mm Nikon user, I am unfamiliar with this type of medium format cameras.  I can tell however that this is a lovely looking camera, with a few marks on it, commensurate with it's age, Some of the black leather is coming off.

The shutter fires when the lever is pressed but on the slower shutter speeds it seems to hang open. The faster speeds are ok. The dials and levers feel normal when operated and everything works smoothly. As with any older camera like this that has been stored for years it will likely be in need of cleaning and servicing so expect that. Overall a very nice, unique camera!

It has a Rollei-hellblou Frank & Heideckt 28.5 lens covering the main lens. This might be a skylight type filter lens, used to keep the main lens clean and free from scratches. It also comes with a Rollei metal lens hood and of course the leather case.
