Just buttoned up this little sweetie-pie about an hour ago. My 1970 Nikon F, I paid a pretty penny for a few months ago. I got it in very good working condition, but could see it had never been serviced. I did'nt want to go around shooting a motor drive on a dry camera. So I spent the last week giving it a total strip-down, clean, lube, and calibration. Seems like the action is smother and the shutter is right on the money. The finder was already perfect, so I left it alone. Someday down the road I'll open up the motor drive and see what needs lubrication, I'm proud of this job. Not one chewed-up or missing screw. I doubt a repair expert could tell if it had ever been opened. The motor drive and the body were mated from the factory. An F is not like an F2. On n F2 you can put an MD2 or MD3 on any F2. On the F, the body requires modification and specifically mated to its drive motor.
