Since we are on the subject.... How do you verify that Hasselblad equipment is actually genuine Hasselblad equipment? Case in point - WLF's. The item below is $200, but nothing on it says Hasselblad, and there is no serial number. How do you verify that this isn't a viewfinder from a Kiev 88 for instance?
