Help with double fork unknown to me

[SDGshox]

I received this fork/monster, with an obsys sticker, I guess it's a Sunn, but I don't know anything else, it has brake pivots (so it's old) if someone can give me more information or has the manual I would appreciate it.

It has some stickers on the bottom like a serial number

Sunn obsys Carving
as used 1999 for a number of bikes


I don't have an manual, but technically I would guess it's pretty similar to other Obsys forks.

Thank you very much for your contribution

Does anyone have the manual? I'm dying to take it apart and do maintenance on it.
