Mamiya 7II: Replacing Shattered Viewfinder and Frame Finder Glass

This has been a week for replacing broken Mamiya 7 viewfinder glass on a number of bodies. This particular Mamiya 7II was very unlucky, both the viewfinder glass and the frame finder glass shattered.
A time consuming task of replacing the broken glass is removing the old bits from the top cover. The glass is glued in place as so care needs to be taken to scrape out all the shards of glass. After all the glass is removed, I fit newly fabricated windows and glue them in place.
After an impact of this type, the rangefinder is often not correct and so it gets calibrated while the top cover is off and access is available for all rangefinder distances (one meter, infinity and vertical).
Last photo shows the camera much happier.
