To keep in mind, a quality overhaul of a Rolleicord, by someone who specializes in Rollei, will run about $125, and will include complete teardown and cleaning of the shutter blades, adjusting optical axis and focus, straightening the back, and replacement of dubious parts with quality parts on hand, and the camera will then work properly for years and yearsa bargain. A similar overhaul of a Rollei might be the same, or possibly double if the more complicated transport mechanism needs to be overhauled.
A regular cla might get the Rollei up and running, only to result in a sticky shutter and broken heart shortly thereafter.
