So this is the news: not a company but a single mechanic with a workshop. His name is Simon Wyss, I have been there couple days ago. He has a lathe, a milling machine, drill press, motor saw, grinding equipment, vices, and more stuff and views over the river Rhine. Beautiful, I must say. He told me that his collimator is being calibrated in England. I saw a Cine-Kodak Special, a sewing machine, an old cinema slide projector with carbon arc lamp, lenses, chemicals, and so on. Possibility to wind and secure spiral springs
