Help with insulator

[HunterTheFox59]

Does anyone know anything about this insulator? It reads Fred M. Locke Victor NY No 14 pat May 22, 1894. I'm curious if it's anything rare.

It's a CD 202, not rare.

Not rare, but far better than the ordinary common piece. One in good shape is about 20-30 dollars.

The one piece transposition patent covered this type of insulator that was capable of holding two wires. On a telephone line, parallel wires resulted in "cross-talk." The solution required crossing the wires at intervals, using transposition insulators like this one.

That is a CD 205 and books for $10 to $40 in VNM condition and various shades of aqua.
