I bought a great M3 from Mr. Hansen when he was still on Madison Avenue. What a charming man! I paid $700 for the camera and a case. After I paid, he said, "Anything else?" I answered feebly, " Noooo." He laughed and said, "Are you sure?" So I got an MR meter also. As he wrapped it up, he said, "People are asking ridiculous prices for those things," and let me have one for twenty bucks.
BTW, I'm taking that set very soon to photograph/see the new part of Penn Station.
