Klein RockShox Fork (Replacement Parts for Internals?)

[Cypher]

Need Help with Fork I.D (Sorry for poor picture)

Was wondering if anyone knows specifically which model of Rockshox this is,
It has 2 identical numeric dials on each side. I was considering converting it to spring or to at least buy a set of rebuild kit in case it decides to give up

I think it is a rock shox Mag 21

...., or Mag 20

the Mag 20/21 are both air/oildamped - I guess no spring set available for this forks, as far as I know. A long travel kit was available BITD which converted the fork from arround 40mm traval to 60mm.
For rebuilding the Mags you need special removal tools.

Oh No..so what happens to those that do not function anymore?? Now I don't dare to ride it :?

The fork brace looks a little bit beefier so I'd say 1993 Mag 21.

TF Tuned for example is able to service them but you need to provide the parts like new seals etc.
