Thanks Paul: The K&E magazine article and pictures describe/show the device I have. On mine,the funnel top and its tip have been refined, and the pouring spout in my basin has further improvement. I previously said that the jug was rigidly attached to the bottom of the wood box. I showed the entire outfit to a machinist last night and he could not believe that the jug was not removable. To explain, there are very unusual screws that go through the bottom of the box into the bottom of the jug (so I thought). My machinist friend put a wrench onto the jug, and with a tap on the wrench the jug came loose. Ingeniously....the jug has an "internal" thread on its recessed bottom. There is a fine threaded plate (like on an old transit or level) that is actually attached to the bottom of the box. The jug screws onto the plate. Pretty neat and makes good sense. My machinist friend thinks the funnel top could be some special type of cast steel? Its polished top, fine screws, and shape makes him question that it is cast iron. Who knows? My research continues with all help greatly appreciated. Thanks again Bruce ----- Original Message ----- From: "Paul Hirose"
