I have a TTL Metering Prism for the Pentacon Six TL that is really dirty inside. How do I open it for cleaning? Thank you.

Here is how I think I opened mine. I don't have a repair manual and these directions may be wrong. Be carefull not to strip screw heads or screws. Remove film speed indicator on top of the metering prism after unscrewing stainless center screw (has two holes on top).
Under the film speed indicator: remove the two washers and the disk that has an up facing prong.
Undo 3 black screws (not visible until after removal of pronged disk) holding the shutter speed knob. Remove shutter speed knob.
Remove apeture knob held on by two screws.
Eye-piece-mask knob has a screw under the small piece of leather in the center.
Remove eye-piece-mask knob and eye-piece-mask knob washer
undo two stainless screws lateral to the eye-piece.
undo front screw under the lower edge of the largest piece of leather below the tower.
The meter can be adjusted using four variable resisters covered by the the small piece of leather on the top surface of the prism (adjacent the knobs)
I don't know the procedure.
