I have for sale my United States Lighthouse Establishment Chelsea 4 1/2\" clock. Serial Number 38313 matches both case and movement.  This clock was made by Chelsea around 1907. Every lighthouse in America had one of these clocks in them at one time. The face is engraved not screen printed. It says Chelsea Clock Co. Boston, U.S.A.and underneath is U.S.L.H. Estab.It is a key wound clock but I do not have the key for it. I used a universal clock key I have to wind it up and it runs beautifully. It is chrome over brass and is in it\'s original condition. There are scratches on the case as can be seen in the pictures.The nickel plating is wearing thin in places but is still a wonderful clock. I\'m sure you could send it back to Chelsea for a complete case rework but I prefer my clocks to be in original condition. The movement is immaculate condition and once again can be seen in the pictures.If you have questions please do not hesitate to ask before offerding.Thanks for your interest!Good luck offerding!
