This is a CD 131.4 [010] - embossed (front skirt) L.G.T.& CO. (rear skirt) PAT JAN 25 1870/PAT FEB 22 1870 - I do not see any periods on this one...and the F is missing the lower horizontal line. Embossing is good and crisp. There is a mold line over the dome.

This cool piece has some milky snot that swirls around the dome. There is some light graphite looking lines/bubbles through the embossing at the rear.

This piece is in very good condition. Above the front embossing there is an area at the wire groove that looks like it touched something while the glass was still hot and there is a small scuffed area. Below the front embossing there is shallow flake above the base - about 1/4" wide. At the rear of the insulator there are a couple of flakes at the base - the widest is about 1/4" wide and they are quite shallow. Near the side there is an 1/8" flake. There is a slight overpour of glass around the edge of the base - some of this has some minor roughness/chipping of the overpour. It is a nice piece!

This insulator would look good at your house!!

This piece can be yours for $165 - includes shipping and insurance in the US (will work with those from Canada). Payment can be made by check, money order or PayPal.
