I think you have to look at things in the context of the time.
There was little or no CAD and books were done with photo typesetters
(very expensive)
Each page was a kind of photograph called a bromide
Non standard things like logos where also stored on a bromide.
Quite often if you wanted to add a symbol or logo to a page or a drawing
you could go
through a process to get a copy from a master and stick it on the page
(real cut and paste)
or dig out your micrometer and draw it using your normal black ink
drawing pens.

I'm puzzled about the notion
of 'o' not being a perfect circle as I found it to be quite so, at least
on the masthead.
When I did this originally I worked from document scans from
Bitsavers, and
became convinced from those that the bowls were a little narrower than
perfect circles: <http://imgur.com/Xd6rreF.jpg>.
Since then I've got a paper copy of one of the handbooks, so I went today
to get a high-resolution look, and now I agree that they *are* circles, or
intended to be, and the models I used must have been distorted in printing
or scanning: <http://i.imgur.com/WIgagKI.jpg>.
