Here is a superb refurbished Linhof Technika III camera. The camera body, serial #58335, is circa 1955 I believe, you may research it if you like. I replaced the bellows with a new one and I cleaned and lubricated all the body parts.
I cleaned and adjusted the rangefinder coupled with the 135 cam (included), with the 135mm lens (not included) set at the 135mm notch/stop on the bed rails and the 135mm distance scale. The rangefinder worked pretty well with this set-up however this may differ with the lens you use so you may have to shim the lens mount and maybe make some rangefinder adjustments. Of course if you are just using the ground glass viewing screen, you need not worry about all that.
I also replaced the ground glass viewing screen with a new one with a better grid design 6x9cm markings. The cosmetic condition is fair with a few rough spots as seen in the photos. It also comes with some original Linhof information sheets. It does not come with any film holders, filters, lens caps or lens hoods.
