Need help to ID this open pontil. It stands 4 1/2 inch and is 2 inches wide. Found on a colonial house site and in same hole was horse shoes, a bridal, brass skeleton key and two heart locks. Only markings I can make out is QT on front panel and the number 293 on back panel at the base. I do know it's hand blown into mold since it has mold lines and pontil scar. Anyone ever seen anything like this before?
