Here are two insulators that were given to me by the bottle diggers. The embossing is very faint, but the one on the left is a CD 102 PATENT-OTHER [060] and the specimen on the right is a CD 126.3 BROOKFIELD [140] in a light blue. The ICON consensus opinion on the age is 1880's which corresponds to the age of the bottles being recovered at the same level. See pictures of this dump dig [id=62213962]
