Here's a toughie - a scarce dome-embossed PRR CD 191 in a typical Brookfield Old Bridge aqua shade. This one originated from the Canadian prairies where some of these seem to have surfaced for whatever strange reason. As you can see this one has some nasty base flakes - One 1 1/4" long and the other 7/8" long. Now $25 USD plus shipping for this example, which will hopefully do until a better example comes along. 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.
