Bronica 6x7 220 back for GS-1

This back is designed to shoot 6x7cm images on 220 rollfilm- not 120! Although you could probably run 120 through this back, that's a bit of an off-label use, so we can't make any guarantees. That said, it's in good shape, with some cosmetic wear, good function. For the Bronica GS-1 medium format SLR.
