Unique Victorian Hinged Bangle Bracelet Lighthouse, Ship Sun Enamel Design 1879

  

Up for sale is this rather unique old bracelet. The bracelet is spring loaded so it automatically closes around your wrist.

I think it is gold filled or plated. There are no markings other than the patent. Some light signs of wear.

Really not noticeable, see photos. The central medallion measures approx. 42 mm x 50 mm when fully closed.
