My bad. I blinked twice this mooning and realized I misread your
commission number. I saw the TS and then I saw the 18 and made the connection
that
your number was close to mine (TS18xxx) so you probably had the same style
starter. Please disregard. Although readers with early models may take this
to heart.

Then I would hope it is a reluctant bendix. I don't see how you can apply
grease to it without removing it. That's what I did on my MG many years
ago.
It might be a bad spot on the ring gear. Try pushing the car in gear to
turn the engine a bit and see if that changes anything.
