Two Retina I type 118 cameras, only one will be going home, part 01

Two Kodak Retina I type 118 cameras arrived for repair. The owner wants the best one serviced and returned, but which one will it be? Consumables used: I use naphtha (cigarette lighter fluid) for cleaning metal parts. CRC Heavy Duty Lectra Clean for dried grease that the naphtha won’t dissolve. A generic wax and grease remover to soak mechanical parts prior to cleaning in an ultrasonic cleaner. Glass cleaned with normal domestic glass cleaner. Parts are lubricated with a synthetic grease, Inox MX6, Rocol Dry Molybdenum paste, MicroLubrol Helimax XP helicoid grease, or graphite grease as needed. Leatherettes are glued back with Ados F2 adhesive.
