Thanks Stretch. Nice pics of the guts of the timing device. Looks pretty similar to the mechanism in a centrifugal advance distributor.

Got another of the device simply flipped over so I can see what it looks like on the side that faces the rear of the vehicle? Just curious to see what that space looks like with my eyes, since I've only "seen" it with the wire probe thus far.

Picked up the camera but didn't have time to mess with it yesterday.

Thanks again, Stretch. I appreciate your time/replies.
