Found this item on an late 1800's home site. Only thing still left standing is the stacked field stone chimeny. It appears to be lead or some other heavy metal, fairly heavy for its size. It also has some shiny metal coating still left on the front and back. I thought at first maybe a decoration off a piece of furinture but upon closer examination of the back it appears that there is a channel where somehting used to run along the back. No writing or numbers that I can make out. Other than a very light cleaning with soap and water and a extra soft toothbrush no cleaning or polishing has been done.
