Unusual pieces

The Pyrex hunting --and receiving-- has been good lately. First of all, I received a belated Mother's Day gift when I visited Libby in Colorado, and I don't blame her for not wanting to mail this:

The Golden Grapes Cinderella chip and dip set from 1961!!! I SO love that delphite blue color inside. Perfect condition. Also in Colorado, I found these little ramekins or au gratin dishes:

I love red, so I just had to pick these up for $2 each. The bottoms say "Pyrex brand Tableware by Corning." A newer item.

Back in Missouri, I grabbed this item for just $11 at my local antique mall:

This is the Butterfly Gold 4-quart round casserole, with lid. Both are marked #664 and they look completely unused. This thing is BIG! I haven't seen the flat lip on any other item. Finally, try to figure out what the next item is before you scroll down to get the answer:

As you can see, it's about 5 1/2 inches long and looks like blown glass on the inside, making it weighted toward one side. It is clearly labeled PYREX / T.M. REG. U.S. PAT. OFF. / MADE IN U.S.A. and has a metal piece on the end--not a cap; there is a hole in it.

My family members made guesses about this item's function: an old IV bottle? Wine-making equipment? A baby bottle?

Fortunately, the reverse side of the price tag told me what it is: a float for a gravity-feed toilet tank. Yep, that's what it looks like, all right--a toilet tank float! This item is really old, and must have been an early attempt at making Pyrex a commercial product with applications beyond railroad lamps. I bought it, of course, and I have NO idea how I'm going to display it.
