C8 with loose secondary housing

Hi folks,

I've got to do some TLC on a mate's C8. The other night looking through it for the first time, the image revealled a nasty case of miscollimation. When I fit the allen key in one of the three collimation screws I found that the entire secondary mirror housing was loose on the corrector plate.

Removing the corrector plate isn't a problem. I'll mark the corrector plate's current position relative to the tube, that's fine. But how does the secondary's housing actually attach to the corrector plate? I don't notice any other screws on the secondary other than the three collimation screws.

Cheers,

Alex.
