I have several of these Brookfield's, but I cannot identify whether they are CD 162 or CD 162.1.

The shape is comparable to that of the scale drawing of a CD 162.1, but the measurements are that of a CD 162. This particular insulator has a number "8" below the Brookfield embossing, which is typical of a CD 162, not a 162.1.

I'm at a loss to figure this one out. The shape is what is getting me confused. Can someone help me out here??

Thanks!!
