If you have a Pressman D 4x5 you know it's something special, sort of what a Graflex would be if it grew partly into a Linhof Technika: finely machined aluminum body, close tolerances, solidly-built etc. The problem with these is that to upgrade to a modern lens you will find your rangefinder is off. The excellent Graflex.org has instructions for adjusting the Kalart Rangefinder, but information on the (better, IMO) Bolex Vue-Focus Rangefinder is nearly impossible to find. After a bit of looking I have found the manual, which includes adjusting the rangefinder for the original lens, readjusting for a new lens, and also info on the focusing light. I've owned and used a Pressman D for six years, and now I can finally use the rangefinder with my 135mm Sironar-N. If you are in a similar situation, I'll mail you a xerox of the manual for $4. Just Paypal me. It tells which screws NOT to mess with, has diagrams, etc. I hope this will help other Pressman users. Just be warned: you'll have to work at the adjusting process a bit (infinity, 6 feet, infinity again, etc.), and it may not work for very short or long lenses. Eyeballing it I'm guessing 90mm-210mm may be the range of the brass focus linkage. I CAN say that at f/16 the original 127mm Ektar has been spot on for handheld work, so theoretically the rangefinder should be capable of fair accuracy, and it's a heck of a lot easier than finding Tech III/IV cams that work with new lenses.
