Okay, here's what I'm seeing. Descriptions are all guesses, mostly based on this discussion--and very much open to further discussion!
From the top, roughly clockwise:
Light Blue - bolt head
Red - car lamp socket
Green - variable air capacitor
Cyan - loose wire
Purple - eraser shield (or similar)
Orange - coiled wire (or spring?)
Gold - too dark to see
Magenta - panel meter needle assembly? *
Yellow - beveled plate **
Dark blue - conduit clamp ***
Dark green - conduit clamp screw
* Here I'm adding a few more parts to the conversation: the magenta part looks to me like a panel meter needle assembly, something like the one in the middle of this, with a pointer that bends twice in the middle for clearance:
It's possible that the magenta area is multiple parts cobbled together, but if we assume it's one bit glued on, I think it is probably one of these -- maybe from a car dashboard?
** There appears to be a flat plate with a beveled top behind the "pulley" shape (*** that I'm guessing is half a conduit clamp) - plate shown here in yellow. Roughly the shape of a hand plane or chisel blade, though hopefully made from something less dangerous!
By the way, I'm not convinced that the plate on the far right is actually an eraser shield, but I do agree that the coil seems to thread through a slot or holes in it, so it probably does at least resemble one.
