If the original bellows on your Omega C-67 or Super Chromega C Dichroic enlarger has cracked, split, torn, developed pin holes, or is in otherwise poor condition, this is the correct replacement. The bellows are supplied complete with the metal frames at the top and bottom, ready to install on the enlarger. These bellows assemblies are used, but have been cleaned, carefully inspected, and are certified to be in perfect working condition.
