Here's a duguesne 106.1 in a nice shade of cornflower blue. It's marked, "Duquesne." on the front skirt, and "Glass. Co." on the rear skirt along with a number on the dome. As for condition, it's got a big ole' flat base chip that spans about 1/3 of the base. Long chip, but it doesn't hardly extend above the mold line around the base. If you can't see it in the picture i've got one i can send of it. Other than that, the insulators in pretty good shape, would make a good piece for someone who doesn't have one already . I'm asking $55 + shipping for this insulator, payment by check preferably. SOLD
