Here's a pair of uncommon Canadian Porcelain-made cables. At left is a white example of U-2583 with no markings, and a bit of crude pitting on the ears as shown. At right is an offwhite/cream U-2421 with a CP incuse marking. Marked examples of this style in white shades have proven to be scarce.

Both are mint from what I can see.

I'm asking $35 USD each or $60 for the pair, plus actual shipping cost. 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.
