Lot#49 LGT CD 131.4 Insulator found along the UPRR - Wyoming This nice Blue Aqua insulator was found along the old UPRR line around Rawlins Wyoming (about 10 years ago). The embossing reads: "LGT & Co" (back) "PAT. JAN 25 1870"/ "PAT. FEB 22 1870". The only damage is a dime size freeze dimple on the dome. I had the insulator tumbled and the frozen glass fell out of the small dimple. $145 + Shipping.
