Hi Conrad.. I want to point out corrections..

Coleshill, Warwickshire.. Should be upgraded from Village to Town.

Remove Edgbaston from Warwickshire (They are in Birmingham)

These towns/Village should transfer from Staffordshire to Warwickshire..

Kingsbury
No Man's Heath
Polesworth
Dordon
Newton Regis
Birchmoor
Warton
Piccadilly

I know their postcode same as Tamworth, Staffordshire but they are actually in Warwickshire.
