Here's a nice 1860s blue aqua Montreal Telegaph threadless insulator embossed on the base Rim: M.T. Co.  There's some typical base nibbling and light chipping, plus a thumb-size slice going up the side of the skirt, as shown in the second pic. A solid example that displays very nicely. Photos are taken in direct sunlight, so the color will exhibit slightly less blue if displayed in a back lit display.

Please view all photos, read the description and ask any questions before bidding.

Please provide payment within 24 hours of the close of the auction. I will combine shipping with other items we currently have listed. Most of all, have fun bidding!
