Sheboygan - Weiss & Walters field jug made by Gunther

Very large (7 or 8 gallon) salt glazed field jug with a Gunther style cobalt flower decoration and stamp that reads "WEISS & WALTERS SHEBOYGAN" and a spigot hole. The piece was made by Guther or Gunther & Berns for a local merchant. This outstanding piece is the only example I am aware of.
