The only ident I really can't remember is the one for Westward TV, which I don't think I've seen before. It served the far South West of England and I believe it produced Treasure Hunt, but it was certainly one of the smaller ITV franchises.
I could not find any idents available for Harlech (which became HTV West and HTV Wales in 1974) or Ulster TV which served Northern Ireland.
So which is your favourite ident? I definitely think the ATV is probably my favourite. Of course, I'm biased as it was my region, but the horns and the eye shaped graphics were very bold. It became Central on 1st January 1982.
Anyway, here is the full list if the 1970s idents in chronological order. Please note that the counties listed are only a rough guide as parts of some counties received signals from different transmitters. Of course, if you were lucky you lived in an overlapping area where you could pick up a signal from two transmitters, although this was more useful for an indoor aerial which you could point in the desired direction.

Thames - served the London area during weekdays.
Southern - South and South East of England inc. Kent, Sussex.
