This is Hemingray No. 40 glass insulator. They were made from 1910-1921 and for use in telegraph wires. This is also known as style CD 152.
It is a bit dark as it is covered with what is called Train Smoke. Steam locomotives tend to produce a lot of smoke, could be from other sources but it is still call train smoke. It is not easy to remove but I have gotten quite a bit off. You are supposed to use and acid or base bath to remove it but I am cheating.

I've never heard the contaminant called Train Smoke. A healthy steam engine won't produce a highly sooty smoke that would deposit like that.
SpiritBear here is where got the term "train smoke"....

Could be constant exposure to the train smoke could cause this like the signs on the LA freeways are stained with diesel smoke.. But anyway I didn't come up with the term. Whatever it is it really hard to remove.
