Both of my Rolleiflexes were overhauled by Harry Fleenor just before I bought them (the camera store, now defunct, used him for all their Rollei repairs). They work beautifully. I've dealt personally with Krikor Maralian. I needed corrective diopters for the magnifier, otherwise I couldn't focus accurately, and he happened to have exactly what I needed. Dealing with him was a pleasure, he searched his stock and called me back, real old-fashioned personal service.
