Getting to the bottom of it.

First up is the mainshaft bearing housing.
The inside of the case, the scribe points to the area that was chock full of grit and crud.
Next is the main bearing, still in the case, the bigger circlip pliers I picked up yesterday were still 10-12mm too small to reach the two holes...
The next two are some brass shims from inside the clutch, the source of the bits I found in the case, and the spring cups, they have seen better days.
The clutch dismantling work area.
The next three is the rear brake actuating arm, I have never seen grease in this condition before, hard to describe but none the less a good clean is in order. The little bolt on the pivot arm part has been bashed to spread it and ground down in such a way that it can't be taken apart, the upside is it won't come undone and cause brake failure at 90kmph.
Lastly all the bits having a petrol bath, all except the clutch corks that is.
So all I need to get out now is the main bearing and give the lot a damn good clean and begin the rebuilding process. My flyside case should arrive by this time next week, by the look of the photo, it will need to be media blasted back to its former glory.
