The Pace forks look like the RC35AB (atmosphere balanced ie there is a hole drilled in them to let the air out I think) ones, I think these were the second generation RC35s. If they have a tubular steel brace on the back they are the first RC35ABs, probably 1992. They might feel like they have no travel but in my recollection you won't improve it much with new elastomers, when I had mine BITD I changed the bumpers about two or three times and never got much more than 40mm out of them I think. But they were way stiffer than Mag20s and the other suspension forks around then.
What else has it got on it? Looks like a nice USE post...
