Here's a nice example of a Canadian Porcelain U-2421 cable with an exceptional light blue glaze with darker mottling and drips. This may have been a primitive attempt to make a "sky tone" glaze. If you like character glazes then this is a great piece!

This one is in VNM condition with just some scuffing and a couple micro fleabites in the saddle groove.

Now asking $18USD plus shipping. 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.
