Unauthenticated Anomalies

The lens shown below, from the serial number, is clearly a prototype, but one that to me is an orphan. The rear gearing and focusing cam look similar to those of the Ektra lenses, except that this lens doesn't have the locking collar necessary to attach it to the Ektra. Kodak supplied lenses for the first Hasselblads and an 80mm would have been a natural fit for a 6x6 format, but it's hard to imagine how this neat collapsible design would have cleared the mirror of an SLR. Its mount also looks little like the lens mount used on the Hasselblad 1000.
