at that time. Higher quality of camera lenses, and of photographic emulsions and 
increased skill of draughtsmen allowed this change to the most economic values 
of the scales. 
All further large-scale plotting has been carried out in one of the stereoscopic 
restitution machines either Stereoplanigraph C4, C5 or Wild A5 and AT.
