Here's an uncommon Canadian CD 143. This is the variant the guide book lists as the No Embossing Canada RB/MLOB "Low Wire Groove Variant". As you can see, the wire groove is substantially lower than the more common RB/MLOB CD 143s. This example has some nice milky wisps in the dome above the pinhole.

This example is in good condition with just a single 6 mm flake on the upper wire ridge of one side. Otherwise it just has the typical sharp inner base edge roughness and a couple tiny flakes. It's nice and shiny overall and would make a great collection addition.

I'm now asking $30 USD plus shipping for this example. I'm always happy to trade for early Canadian glass or Canadian-made porcelain insulators. I have a long-standing want list of Canadian-made porcelain posted, [id=505519866; please click here to see it]. 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.
