"Empire Bronze Portico Clock"
A 19th-century Empire-style gilt bronze portico clock resting on a black marble base and four small bronze feet. Richly ornamented in bronze, this type of clock is more commonly found in brass. Working condition not guaranteed; sold as is, requiring servicing. I believe the item pictured is part of the pendulum. There is a small chip in one corner of the base. No key or bell.
