These G.N.W. CD 143s are a bit perplexing to most Canadians. They're really quite scarce and don't turn up often at all. I for one rarely see them surface, and when they do they tend to be in very poor condition. Most examples I do see turn up are shades of aqua or light green, and just about any other colour is very difficult to find. I think most Canadians feel they're a bit undervalued in the hobby, and I agree. In any case, here's a pair of them available for purchase. Neither are perfect as is often the case with these GNW CD 143s, but they're still great specimens for their age, scarcity, and aesthetic appeal.

At left is an example in a light yellow green colour. It has a few good-sized bubbles in the front crown and some from manufacture "crazing" fractures in the threads that give it some extra character. This one is far from perfect, with an 8 cm long flat flake in the rear and an associated 2.5 cm tall vertical fracture that runs off its centre point. It also has a couple vertical flat flakes off the skirt around the base edge, but fortunately none of these show from the front.

At right is a greenish aqua example with some great milky line that run throughout the front skirt. It has a 2 cm tall fracture in the front skirt that may be from the annealing process as it doesn't seem to be associated with any impacts. Additionally there are two flat flakes on the rear base, one about 1 cm wide and the other about 1.5 cm wide.

I'm asking $45 USD for the pair, plus actual shipping cost from London, Ontario. 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.
