This back has a matching insert. Backs and inserts were finely adjusted as a pair at the factory, to ensure a perfect image. The inserts were marked with the serial number so that they could be identified. The A-12 magazine was designed to improve the relatively slow film loading procedure of the earlier version (C12) of the magazine. There were also complaints that the very fast film could be fogged through the viewing port on the previous version. The new design introduced in 1968 addressed both of these problems. A winding crank and the absence of a viewing port are the obvious items that identifies the A12. An additional change is a hinged film reminder that holds the end flap of 120 film boxes. At photo conventions and events, Hasselblad used to sponsor film loading competitions for photographers, The fastest competitors could load a film onto a A12 in about 10 seconds from film in one hand and magazine in the other; to the film loaded, advanced and clipped onto a camera body!The A12 was all chrome until 1973 after which both black and chrome versions were available, numbered 30074 and 30147 respectively.
