Hasselblad 500 C C/M A-12 black 6X6 film back. Numbers matching, working well, cosmetic wear. Slide slightly wavy, works OK.
Good way to keep ahead of film changes. Magazine 12 6X6 chrome film back. Although everyone calls these "A12, " they aren't really A12s as I'll explain later. The original magazines are simply called Magazine 12.
These work great on all Hasselblads. They load a little differently. You don't need to line up any arrows; you simply thread the film and close the back. Open the rear film reminder cover to see the film's paper backing through the long silver peephole.
Flip out the winding crank seen above and wind it quite a few turns until you see the first "1" on the film backing. Close the peephole and rotate the crank backwards (counterclockwise) which clicks the number "1" into the window below the crank. Two advantages of these old magazines is that you can plug the peephole and use a Rube-Goldberg style procedure to shoot 220 film in them for 24 exposures, and that you can see the film moving through the peephole if you're unsure. You can see the film backing through the peephole, but there is no moving red bar on the left side to show film motion as there is on the newer magazines.
You set film speed as a reminder on the back, as well as film type. There are icons for B&W, and for four kinds of color film: positive or negative and tungsten or daylight.
