Spare set of genuine replacement bellows for the Bellows assembly on a Bowens Illumitran Slide Duplicator. If you have an old tatty pair these are easy to replace. All you need is a small jewellers screwdriver. Unscrew four screws at each side to detach the old set from the lens and body panels and screw the new set back in place. I have spare screws if you lose or damage one.
