Thanks to a friend I have now a Contax IIa (plus a IIIa as bonus) "serviceable", if I add to this equation the variables "no wife" + "no dogs" =
I cleaned and lubed already the slow gear, so speeds should be fine, I test all of them and they seem ok.
On my way to dismount the rangefinder two small sims felt from I-don't-know-where, my guess they belong to the helicoid plate that holds the lens, but from which of those five screws come from these two sims?
Another question if you can help me is how can I clean the "yellow" glass of the rangefinder? OR is it better leave it if I have no problem to focus?
Tomorrow will be the cleaning of all the metal parts disassembled and the cleaning and lubing again the rangefinder and helicoid.
Thank you for watching and the advices.
