I was about to say, yours is a post ford by the sounds of things

[b]Pre Ford badge[/b] - wings badge only came on the 98 models
[b]Unbadged steering wheel[/b] - badged wheel only came on the 98 models
[b]Koito lights[/b] - bosch lights only came on the 98 models
[b]Old style heater panel[/b] - pic?
[b]Instrument panel dimmer wheel & headlight adjustment wheel[/b] - came on both pre and post fords
[b]Flowery seats (but dark blue, so pattern not really noticeable)[/b] - post ford seats
[b]Vinyl seat backs[/b] - option I think?
[b]No map pocket in passenger seat[/b] - none of my post fords had one either!
[b]No puddle lights[/b] - post fords didnt have them
[b]Light in door lock[/b] - post ford only
[b]Rubber gear stick gaitor (looks awful, recesses continually collect dust & crap)[/b] - pre and post ford - leather was an option!
[b]Deep door pockets with no lids[/b] - post ford
[b]Boot release by driver's seat; no push release button in back panel[/b] - post ford
[b]Proper lever for seat adjustment (i.e. not just a cable)[/b] - post ford
[b]Black strips on doors[/b] - post ford
[b]No coolant pipes[/b] - you mean aircon pipes? thats just it not having aircon

[b]High level brake light[/b] - post ford
[b]Wing mirrors black plastic, backs not colour matched to body (or is it shape that determines pre/post?) - anyway, they have an amazing range of vision so I presume pre-Ford.[/b] - as Matt says, groove in the back is post ford, smooth is pre-ford

sounds like you have a post ford car entirely, other than maybe the heater control panel

EDIT: The heater panel was the same in all Fs apart from the really early pre fords, it would seem! Most had the style all of mine have had:
