Yes, okay.

hmmmmmmm

And overlaying the shifted waveform back ontop of the original one?

That's like mixing two tapes together, with one tape slightly delayed
in comparison to the other.

This is the part I am curious about. Obviously you wouldn't want to
delay one tape so much that there is an echo, but if you can control
the relative speeds of both tapes before mixing, that would be the
way to do it. If you have lots of different instruments recorded
separately, on their own separate tapes, which admit to flanging better
than others? Woodwinds? And as for recordings that are played
backwards, don't flutes or oboes sound very similar whether they are
playing forward or backward? The whooshing flange sound ought to
easily distinguished from backwards playbacks, I guess, but I don't
have that refined of an ear.

Certainly worth looking into.

For those of us who can remember the olden days with ring modulation
of sound samples at tenths of a second observing sawtooth waveforms -
c'mon, there's got to be a lot of us out there who can, anybody who
has a used 8 bit computer in an attic can do that - would it be
something like that?
Perhaps somebody out there can suggest more examples of 60s hits
with flanging in them? Is there a comprehensive list out there
somewhere?
