Re:
I agree with the above post, it is probably a '99 or '00. Looks like a SID dual air SL model, but can't tell for sure without more pictures. In any event seal kits for these forks, i.e. 28mm sanctions, are getting hard to find at least in the US. I've seen them on eBay being shipped from some where in Asia. Not too expensive but takes a long time to get them. These kits do NOT come dust wipers or crush washers, both which are easy to find else where.
If you are going to rebuild, I would take it apart first and make sure the parts for your fork match what the rebuild kit shows. I've notice two kits that are listed for 00-08 28mm forks, have different parts. One matched what I had, the other not so such.
in any event good luck
