Never heard of a green XC700, so probably it is a DH3 you encountered. Pretty sure Retrobikeguy was selling such a green/red configuration recently.
DH3 came in red and green. I do have a green pair. They are great forks. It is in my Koga Miyata SkyExpension downhill machine currently. My Verlicchi/Iron Horse has XC700s.
xc700s & DH3 :
Marzocchi still sevices those forks, what imo makes them morally superior to apparently disposibles producing/unvironmental unfriendly Rock Shox & others
