Help identifying old RockShox fork

[Nuffy]

I’m hoping somebody might be able to help me identify this old 26 inch RockShox fork. I’m guessing it’s from around 2005 to 2008. It has “05” stamped onto the underside of the crown, so I’m not sure if that’s the year model? I can’t see a serial number anywhere.

It has a straight steel steerer tube, IS disc brake mounts and no V-brake mounts, 85–130 mm U-turn travel adjust, coil spring, and Motion Control damper with remote spool. My research so far seems to suggest that there were Pikes, Revelations, Rebas, Recons, and Toras around that era that match most of these sepcs. I don’t think the lowers match the shape of the Pikes, but I’m not sure which of the others it is.

My main reason for wanting to positively ID it is to get the oil volume for the damper, as I’d like to service that. Alternatively, is there an easy way to calculate the oil volume based on the dimensions of the stanchions, damper shaft, and Motion Control unit? My guess is that the oil should just submerge the bottom of the compression damping unit when upright and static at full extension, but I’m not certain about that.

Most of those 26" forks used between 130 and 150ml in the damper.

Pour oil into the into the stanchion, cover the top and cycle the rebound. Extend and then adjust the level so that when you fit damper you cover the foot of the cartridge.

Something like in the pic.

That crown makes me think it's a Tora, but that's mostly academic.

Just use oil height - 10 - 20mm above the damper foot at full damper extension. Cycle the damper a few times to get the bubbles out from under the rebound piston before you measure.

And replace wipers while you're at it or you'll be replacing the fork pretty soon.

Thanks @David Marshall and @droo for your helpful responses. That’s much what I suspected, but it’s good to have it confirmed. I’ll crack on with it then.
