General Condition: 
The body is in overall very good condition, with minor signs of previous use.
The original leather covering is in very good condition. 
The focusing hood works great as it should.
The focussing screen has been replaced in the past (probably around 1980-90) with a brighter plastic one. We find it very comfortable to use even in bright sunny day. It is in good condition despite having some light scratches at the bottom (we don't find this intrusive).
Both  lenses are in excellent condition. no fungi, haze,  separation or scratches..
The Synchro-compur shutter has been cleaned and re-lubricated  and now works very well at all speeds. 
The self timer is operational .
The flash connection has been tested and works fine.
What we've done:
We did a full overhaul of the camera.
The front and the optical elements have been disassembled and cleaned up.
The cranking system  has been assed, cleaned up, lubricated and tested.
Same for the focussing sytem which has been adjusted after cleaning and re-lubrication.
We fully checked the camera and all movements are  fine.
