Hello. I managed to score a Perfex Speed Candid for $3.00 a while back at, of all things, a car parts swap meet. In fact, it was at the same place where I bought the Honda CL450 motorcycle that I photographed with the Leica IIIa in an earlier posting. However, unlike the solidly engineered and built Honda, the Perfex is in need of loving care. I would appreciate help on the following things: 1. What is the size of the winding knob? It is missing in my example. I need to know the size (width and height) of the original so I can have a new one fabricated. A close-up picture would also be nice. 2. How hard is a shutter curtain replacement? This example's second curtain is badly wrinkled, and leaks light. The shutter itself works fine, but the curtain needs replaced. 3. Is the shutter coupled with the film winding, i.e. does winding the film cock the shutter? I have yet to disassemble the camera, and was wondering if the shutter needed to be cocked by winding the shutter knob, as well as needing the film wound seperately. Seems like a complicated, un-ergonomic camera to use. Wind the film, WIND the shutter to cock it, determine exposure through extinction meter, calculate exposure through exposure calculator on back, select the shutter speed, select f-stop, focus the lens with uncoupled rangefinder (missing on my example), transfer focus setting to lens, look through viewfinder on FAR RIGHT of camera, and take picture by pushing shutter release on FRONT LEFT. Then again, I like a good challenge!!! Thanks for your time!!!
