Washington Pottery toilet tank, dates to around 1930. This particular manufacturer tended to put heavy glaze on their product, and that makes reading the date code impossible. Washington Pottery merged with Eljer sometime in the mid 1930’s, so Eljer bowls of the same time period are a good color match. This tank measures 21 1/2″ wide by 17 1/2″ tall and extends out 7 1/2″. All measurements include lid. Tank outlet is 4 1/2″ away from wall. Condition is excellent original condition, no chips or flaws.
