Nice find. Boots on it means someone played with it.
Sold a bunch of those, seemed like a production line at one point. Does anyone remember drilling the fork legs to "improve" performance on these things?
Acquired one of those recently too, though not as "clean" as yours. The elastomers liquified, leaked and re-hardened leaving a sticky blue goo in the box and on the manual. I hate the chore of cleaning them out.
Nearly finished cleaning up my pre-Answer Mani Ones, though. Ready for new elastomers, reassembly and installation on a proper vintage steed.
