Hasselblad A12 film magazine (6x6, 12 exposures). I used it with a 500CM, but I'm selling it because I've sold the body. I was using it without any problems until just recently. An optional dark slide holder is attached to the back. The dark slide is a little stiff to insert and remove, but it wasn't bothersome when taking pictures. Also, there is some rust on the knob of the film holder key (photo 7). I've been using it for about 5 years since I got it, and the rust was there when I got it, and it hasn't progressed. Aside from that, there is no peeling of the leather, and I think the condition is average. Please purchase only if you understand that this is a used item. *I am not accepting price negotiations.
