Magnetism due to electricity needed a separate symbol.
Later the simple model based on "poles" (= magnetic

Not true. See Jackson (1975), p.252 (explaining Dirac).

On the next page, Jackson asserts:
"Since the symmetries of rho sub m under both spatial inversion and time
reversal are opposite to those of rho sub e, it is a necessary consequence
of the existance of a particle with both magnetic and electric charges
that space inversion and time reversal are no longer valid symmetries of
the laws of physics." [followed by conditionals...]

Interesting.
