Good advice. Someone will jump in and share how they got their Rolleiflex CLA done for $120 or so at some general camera repair place and that is great. Good for them. But all they got likely was some lubricant squirted on the shutter and infinity focus tested. For these babies in my opinion they need a real overhaul and true deep CLA and that costs at least what TFC quoted above from a good Rolleiflex or at least TLR specialist repair technician.
