I picked up a Kodak Regent II folder with a Xenar 10.5cm f/3.5 lens and integrated rangefinder for $5 at a thrift store. The focus knob doesn't work (I can see the mechanism is not connected to anything under the bellows), the shutter doesn't fire (doesn't even cock actually), and the lens is hazy. Do you think it's possible to get this fixed up into usable condition, and is it worthwhile? If so, who might be able to do it?
