Yup, A guy I know was in the aerospace fabrication business 
(now retired).  A few years back, he showed us some horribly 
degraded mylar plots of some military aircraft drawings that 
were all the manufacturer could come up with.  The Air Force 
was doing a major rebuild of those airframes, and needed 
some skins shaped to replace the tailplane airfoils.  He 
knew where possibly the only airfoil bender was, and quickly 
bought it from a scrap dealer. They then had to scrutinize 
the plots and try to extract the original dimensions so they 
could bend the skin to the required shape.  Lucky the 
original manufacturer at least had some form of document 
still available, or they would have had to do some 3D 
scanning of an existing part that was not too far gone.
