This sad iron trivet was manufactured by Griswold, but the Griswold name is not on the piece. It is marked only with the pattern number, which is 1604. In “as found” clean condition. Some excess Japanning or paint on the bottom in some areas. Please see photos. Sits flat on three stubby feet. 5-7/8″ long x 41/4-” wide at widest, 3/4″ tall.
Clean, Japanning appears intact.
