Hi all, new to the forum! I’d be grateful for any assistance in identifying this Hasselblad Camera variant I picked up along with some other manual bodies. See attached photos - it’s almost like a 553ELX but it has a different battery door not unlike the specialist NASA cameras. It is black but some panels have a Matte-black solid panel in place of what would normally be leather. It looks similar to the Space Shuttle ELS model, takes AA batteries and the serial number starts RH so 1982? Anyone out there with any serial number info for the space models able to comment? Or maybe a prototype? Thanks in advance!
