from the early 90's the marin models had different colours they kept even through changes, so Eldridge Grade, started red forks and letters, then red chain stays and letters, then red lettering and bits when more chrome.
Orange = Pine
Red = Eldridge
Green = Palisades ??
and Pink was Team but I think most of the Rockstar forks were actually the same just different colour, certainly pine and eldridge were and infact same frame just different bits. So sounds like Team from early 90s but could be need pics to be sure
