O.W. Richardson's "The Electron Theory ..." is really pretty
great, he spends a lot of time explaining all sorts of
issues in systems of units and algebraic quantities and
derivations and the inner and outer and these things,
it's a 100 years old yet I'm glad to be reading it now.

Yes, in those long past times every competent physicist
understood about systems of units and dimensions.
This has been lost as a consequence of general 'SI-only' education.

A more readily accessible (and excellent) source for the subject

Unfortunately the subject is not covered adequately in Wikipedia,

Then I suppose you should walk back what you said
about "Buckingham Pi: dimensionless analysis", also.
Thanks though I've heard of that.
How about Baylis, I've enjoyed reading Baylis,
and in the decades since I first started reading it,
I imagine there's much more to make of it.
