A relatively scarce style here in S.W. Ontario, I haven't come across too many of these Diamond CD 115s - especially in good shape. All of these are the [020] EIN with a diamond on both skirts and smooth base ([010] is VERY tough to find around here!). From left to right: Vivid light green, light aqua, light blue aqua, and light blue aqua with a great harelip next to the embossing on one side as shown.

All of these have some minor condition issues, but all things considered are pretty good for their age. From left to right:

The light green has a pair of flat, 1/4" flakes coming up the skirt from the base on one side and a few other areas of roughness around the sharp outer base edge.

The light aqua example has a tiny 1/8" flake on one side right at the intersection of the top upper wire ridge and side mold line.

The first light blue aqua example has a 1/2" long area of roughness along the uppermost wire ridge on one side.

The second light blue aqua example has two 1/2" long wire ridge flakes on the top and bottom wire ridges of one side - but it displays well from the side with the big harelip!

I'm asking $40 USD plus shipping for the group of four. 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.
