Here's a beautiful CD 234 carnival PYREX T.M. REG.U.S. PAT. OFF. and on the rear is MADE IN U.S.A. with a numeral 63 following. Above the "U" is the letter "R." It's in pristine shape and looks like it just came out of the mold. I can't imagine it being used on a crossarm, but...I've heard stories about them being on a line here and there, so...gotta believe.

It books at $52 and I'll take $40 for it plus postage.
