Mystery Parts

I picked up a few extra parts from somebody who was getting rid of some surplus items. There was a box of unknown items and many were labeled and easy to identify - a few others have me stumped. Some items in the box were from a Commando and some from a P11.

Can anybody help identify these parts?

Triumph swing arm shims I think.

The washers type thing looks familiar. I remember having to make some that were ground flat on one side. Something in my brain tells me it was for the tightening of the forks tubes in triple trees. (Also think it was on my 71 Honda CB500 cafe racer I built.)

Okay, so the flattened shims aren't likely to a Norton. The one that has me really stumped is the unthreaded bolt - it looks more like a hinge pin than a motorcycle part.

I don't think any of this is for a Norton, the only exception is the stud which may be a lower rear engine mounting stud.
