Gear indexing issue

Unless I've misunderstood what you mean by trim control - they are one big trim controller. You can position the shifter wherever you like (and it stays there by friction).

I agree, so maybe I've misremembered.

There were also friction shifters which had a ratchet.

Does anyone recall those having a trim or fine tune control?

Indexed downtube shifters. Dunno I've never used them.

Other than adjusting the cable tension by twiddling the cable stop, no.

Check your wheel is in properly. I once spent many hours trying to work out why I couldn't get the adjustment quite right in both directions. That's all it was in the end.

Campagnolo Record 8speed Syncro downtube shifters had a trim control on the shifter.

I've got 10spd 'Record' bar end shifters on my 653 TT bike,

They have a 'trim adjuster' on the back of the lever, but why do they have 3 places that you can adjust the cable tension

That's a good question, but if you had braze on cable stops you wouldn't have the adjuster on the downtube like you have on your bolt on stops.

Don't tell anyone but they're actually Shimano cable stops, the Campagnolo ones supplied with the levers look like they'd been nicked off a lawnmower carburettor (a 1950s lawnmower at that)

EDIT- See

I've got Suntour Power Friction shifters on two bikes, they have a ratchet mechanism, but only when the lever is pushed down, it functions by using a toothed wheel with a ratchet pressed by a spring. Easy to clean and maintain the inners.
