I have a MX I bought new in 1954. Never had a CLA and works fine. But I am not a pro and I have several other cameras I use. The shutter speeds sound OK, but I am sure they are off. But if I had been a pro, I would have worn it out long ago I am sure. But the 'if it ain't broke, don't fix it' works for me. J Bob C.

What do listers think about having a CLA done periodically on an old but perfectly functioning camera? When I purchased my Automat MX in 1964 from a camera store it had already had a CLA done and it was only a dozen years old or so. I just this year had it gone over because it hadn't been used in 40 years and the focusing seemed a bit stiff. I bought my 3.5F "whiteface" new in 1971 and it has been lightly and infrequently used since. It has been stored in a cool dry closet. The only thing I've done is to clean the meter and selenium cell contacts. It functions perfectly. All shutter speeds and the self timer sound right (and expose correctly). The crank seems a little stiff but not bad. The focusing is smooth and I can't tell if it's stiffer than it was new. My philosophy is generally "if it ain't broke don't fix it", however if I ever do send it in for service it would be to Harry Fleenor. I don't know how much longer Mr Fleenor is going to be active in repair.
