This week I was very surprised to receive as a gift an enlarger, a Meopta Opemus 2A, which I sold more than 30 years ago, and bought new 40, maybe 50, years ago. During all the years since I sold it, it was never used, so I even got my old chemicals, papers etcetera in return. Unfortunately, the last few years it had been kept in an unheated space, so there are some things to do in order to get it in ”perfect” shape again. Among others, the bellows are so stiff that I don’t dare to try to press them together. Furthermore, there is a leakage in one of the bellows' folds.
What are the bellows made of? Is there a way to make the bellows soft again? How do I seal the leakage? Are new bellows or something that can replace them available?
