BIG insulator

[SHERMANVILLE ILLINOIS]

Found in woods, off a demolished building site. Do not think it, (demolition of building), would be more than 10-15 years old, pole was still in good shape.

Big and heavy; entire pole was laying in the woods with this still attached.

Perhaps someone could tell me what the different parts are called. Metal bells above insulators are rated for
"10, 000 LBS", also what appears to be a "B"; reverse side has "82123-131". Anyone know what the proper term would be for the metal bells that sit above porccelain insulators? Would I be correct in the 10-15 year range for age?

all have a good un.............
