I had some Manitou 4's around that year. Nice fork, easy to service, well made & most important looked ACE !! silver n black with shiny silver....
hmmm Might look good on your frame? What colour components you going with?
magura have released their new range of forks in a choice of colours to match retro frames. they also sell 1" steerer versions.
Not quite period i know, but a good option if its going to be a regular ride.
