Around 80mm travel.
I was thinking Pace RC36 Evo III or Pro Class II.
I've put in a bid for some RC36 Pro Class II - can steerers be changed on these?
How about some Marzocchi from around 2001? What's difference between Z1, 2, 3 , 4 etc?
(not a full retro build) ??
Of the Pace forks, Pro Class II are the ones to go for. There are bad leakage problems with Evo IIs and Evo IIIs.
RC38 Air Force forks work well but are not very laterally stiff.
Now I know you're going for a UK project sort of ish so Pace is the logical choice.
However the best fork for small money will be Marzocchi Z2s. They outperform Pace - just a lot heavier. I sold mine on as I had nothing to use them for. But they were very good. Z2 Superflys are good too - but a lot less plush (still have them on my Parkpre)
