I bought my 1955 LEICA M-3 with a 50mm 2.8 collapsible ELMAR in 1968 for$145.00 had it overhauled by LEITZ, N.J. a few years later including converting to single stroke and many other things such as shutter curtains, cams, etc as I recall, (a bit foggy memory at 80) that cost was $250.00. My how things have changed!.
