Actually, the preceding tool combined with

I’d rather guess, he used this technique:
<http://en.wikipedia.org/wiki/Dry_transfer>.
I have used it myself, in the 70s, to insert all those
Greek symbols into the formulae in my Dipl.-Phys. thesis.
It renders much clearer glyphs than the mimeograph
technique.

LetraSet (the market leader at the time) was indeed widely used by the
70s, but was this available as early as the date of the manuscript?
The hallmark are aboslutely indentical shape, but with strong likelihood
of small positioning errors (in both axes and rotation). The latter
should show up on careful examination. Sometimes a letter could "tear"
or the thin foild that could "fold" or "crease" upon transfer. Usually,
in a careful production one would redo the letter, but sometimes such
small imperfections survive - they look very different from defects in
other forms of typography.
