Well, I finally decided to let this one go to a good home. Beautiful delft blue WFG Co Denver. Comparing this to most Denver tolls, this one is exceptionally good glass quality with little to almost no annealing fractures and cracking that is so prevalent among the Denver glass. Has a nice garden pea sized bubble beside COLO in the front skirt and 3 tiny dots under DENVER.Main embossing is crisp and clear with "W.F. / ENVER" ghosted on the domeside like a CREB piece. Only issues with this insulator is that it apparently was dropped to the ground by a lineman numerous years ago causing a very small flake off the edge of the WG lip at the mouldline and has lain there in that spot in the soil leaving a light haze on the glass over the main embossing. This haze will easily polish up with a light buff with buffing compound or a light tumble. Insulator displays mint once it's polished and you'll not be dissappointed with this toll. More pix on req. First mail to me....Book is $125 for delft. My price....$90 delivered in USA/CANADA, other countries, I will assist with part of the shipping costs.
