Not recommended for serious repair of serious vintage cameras. I use Nikons for 35mm work (Nikon F, F2,F4s) and needed a cleaning/tuneup and flash sync check on my Model F. When it was returned, flash had bad shutter sync and owner admitted he had not tested the camera for proper functioning. I verified the sync was off right there in the store (set at 1/60, camera back open, flash fires, check for open FP shutter when flash fires). A new work order was created. Second repair seemed to work. I would not trust any camera service that has a check-box on the work order that says ""No Cost ReDo"". I no longer let them touch ANY of my photo gear, as I consider then less than fully qualified for Nikon.
