Here's a tough-to-find Canadian porcelain beehive style. These "double groove" CPRs seem to have only seen localized use along the CPR system, with examples (that I know of) having surfaced in SW and Eastern Ontario, and New Brunswick. This example came from the collection of the late George Nowacki and was found in New Brunswick along with several other examples. These are a Pittsburgh High Voltage Porcelain product. The marking on this example is quite clear, which is somewhat unusual for one of these.

All I see for damage is a 1/4" lower upper wire ridge flake in the front (make sense of that). There is a fracture in the right side of the skirt but it's obviously from manufacture as it has separated and is partly filled with glaze.

I'm asking $40 USD plus shipping for this example. I'm always happy to trade for early Canadian glass or Canadian-made porcelain insulators. I accept PayPal, or personal cheque from any member of ICON or any collector with whom I have dealt before. Please feel free to contact me with any questions or for more photos, and look through my other items or unsold sales stock to combine shipping on items.
