The photo in the lower center looks a lot like a drive shaft balancing weight for a car. I can't tell from the photo, but if it is curved in the center, as if it would fit the curved surface of a driveshaft, then that may be what it is. If not, then I'm probably way off.
no i believe he means the flat square object with the little dimples in it .. it kind of looks like the weight they use to balance a cars drive shaft..
but even though it does look like 1 it looks smaller then the ones i remember seeing.
