Here is one of my little treasures I have enjoyed for nearly 25 years. This is a reverse orbit Chelsea Pilot House clock (model E if you are looking in Andy's book) made for Chickasaw Shipbuilding on September 22, 1920. It has serial 130166 and in 1997 I wrote Chelsea and got a certificate of origin, which the buyer will receive with the clock to frame or place in a notebook. Clock keeps good time and is a little larger than a typical 6 inch clock. Dial measures 6 3/4 inches in diameter and the case is a hinged bezel type in good condition and has a push button release. The seconds bit is about two inches in diameter and it is the classic sign of the pilot house clock. What is unusual about this clock is that the rear plate of the movement seems to be made of red brass. It also seems the plate was cast as there are casting wrinkles in the plate. Chelsea stamped the serial and their name on it anyway. See the pictures of the movement and you will see what I am talking about. Clock runs a week and comes with a Chelsea key. The dial of this clock is in very nice shape for nearing its 98th birthday. I am moving and cannot take everything with me, so I need to regretfully pass some things on. I will be posting other clocks as time progresses so to speak. Clock is larger than a typical 6 inch clock. Thus shipping will be twenty dollars. Clock comes with a Chelsea key. Domestic sales only. Feel free to ask questions.
