This is a really pretty French Portico, Napoleon III, Regulating Pendulum Clock.  Very nice working clock with lighter wood inlay. It measures 18 3/4" X 9 1/2" X 5". I believe it is from the late 1800's, but I am not a clock person. I am also not sure of the workings, but I put the pendulum on and gave it a nudge and it took off and ran for several minutes until I took it off. Seems to work fine. Comes with Key. This came from an estate of a high end clock and oil lamp collector. She only bought the best. She had a few Tiffany's and some carriage clocks which I purchased as well along with a few others. I will also be listing those so be sure to check my other listings.
