#665 1000 Unembossed. Glass Block. Dark amber.
Passes light through the entire insulator in a north window or with regular artificial back lighting. In a color run of blocks, this one fits right between the lighter amber example sold in Pole Top's December, 2019 auction and the deep amber example also known to exist.
Several variations of the “block” style insulator have been found, dating primarily from the 1840’s to the 1860’s. They were used on two, and possibly three lines which connected the northern states with the Gulf region of the US during the 1840’s. Some were also installed on lines constructed during the US Civil War in the 1860’s, but it's unknown if they were of new production at that time, or if they were reused from earlier installations.
Anyone attempting to assemble a large color run of blocks, or desires to have two or three choice colored examples, this is a "must have" jewel! All the amber shades are quite rare, so this is certainly one to pursue!
Bottom corner has a penny size chip. Three pinkie nail size, shallow flakes on the surface. Otherwise, minor corner flakes. Pretty nice condition for a block!
