Spools??

[Bumpa66]

I found these few pieces over the last year while digging for bottles. Not sure what some of them are. I believe the taller one in the middle is an insulator or spool for a fence post. It has Knox embossed at the top. The other two I don't know. The one on the left looks like some type of wheel to me. The one on the right has a groove embedded in the side and has a hole at the end of the groove. Both sides look exactly the same. Has anyone seen any of these before?

Here's a picture of the one with the groove. [attachment=ceramic pieces2.jpg]

The larger one is definitely an electric fence insulator but used for other purposes also. The other, the one with the groove, looks like an insulated spring affair, probably / perhaps for a machine / devise situation. I enjoy such stuff.

It reminds me of a florescent light end, maybe neon. [8|]
