Here's another scarce early Canadian glass piece: an unembossed CD 133 with a rounded base and MLOB. This example is a nice crisp light blue aqua colour with great clarity.

Condition on this example is relatively good for a piece made c. 1880 or so, but it does have an 8 mm fisheye bruise on one side of the dome, and a stubby 1 cm tall annealing crack in the base on one side. There are two open bubbles on the outer base edge beside the annealing crack. Apart from this damage, this one just has a couple tiny fleabites on the upper wire ridge/lower crown, and some inner base edge roughness as is always found on these RB units.

I'm now asking $50 USD plus shipping for this piece. 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.
