Identifying file format

Has anyone developed a set of criteria by which to identify AutoCAD
plotter pen drawings?  I was recently looking at some very precise
pen and ink architectural drawings and wasn't sure whether they had
been done by hand or by a plotter.  That made me realise that many
of the architectural drawings from the '90s that I've simply
identified as pen and ink may actually have been generated by
AutoCAD.

    answer, but a good place to start is
