<p>M.C., which part of the world <em>do </em>you live in? (I could not derive a clue from last picture made by the Bessa, nor from the picture <em>of </em>the Bessa, where you've so blurred the background that I cannot see what language the books are in!) We have helpful people on this forum in UK, Europe, Australia, NZ, India, and scattered a few other places outside North America. Someone might know of a good repair-person near you. These old folder shutters (Compurs, Prontors, &c.) are somewhat standard, such that many competent technicians ("of a certain age," perhaps I should add) can work on them. It's not like some of the obscure camera models with bizarre proprietary designs, where you'll find that only one person in each hemisphere has specialised on it.<br>
