This is a cool old porcelain threadless hat. It stands 2 3/4" tall. It was tagged by a previous owner: "Dug in Guelph Ont. C. 1860" It does have a fairly large skirt repair, but for this unusual oldie, it looks fine to me. The pinhole is 3/4" across. Nice glaze, though the top has some areas where the piece stuck to something in the kiln. Enjoy
