Photo was taken in natural daylight and in front of a shear curtain. The "lot" numbers (#) help me keep track of insulators they are not embossed with that number.

Lot #20 1871 PATENT CD 125 Insulator I like the massive thick walls on this insulator and the 1871 patent date. There are several nice bubbles. The only damage is a thumb-nail size flat base chip and three flea bites to the upper wire ridge. There is some wire groove ware. Embossed "PATENT" / "DEC. 19 1871" (back) "W.U."/"5"/"A". $10 + shipping

Lot #21 Semi-Rare Light Blue Aqua W.U. Insulator PATENT 1871 This insulator is embossed "PATENT" / "DEC. 19. 1871" / "D" (back) "W. U." (For Western Union) / "5". This is very nice and thick wall insulator. I don't see any damage except for some wire groove scars from the wire and some rust also from the wire. $20 + shipping.
