hard to say -- Zeiss made hundreds, if not thousands, of different cameras-- mckeown's says in one year the catalog showed 104 models with three separate lens/shutter options for each in 1927 or so -- this looks like a small and very simple probably quarter or eighth plate camera that someone put a relatively cheap shutter/lens on. it would take a specialist to identify this particular model -- i don't see anything like it in mckeown's, but they don't claim to have everything by a long shot.
that looks like a rather large mount for a lens for such a small camera -- wonder if it is the zeiss version of the Ermanox, which had an F2 lens, used 2 by 3 glass plates and was used by professionals. That camera had a focal plane shutter. Something like this would have been marketed to the consumer looking for a point-and-shoot.
