This antique frame style is loosely known as a Barbizon frame, named after the French group of artists who often used variations of the style to frame their works. This particular frame does not have the classic Barbizon pattern, the corners and centres are a little to decorative, so it is probably better described as Louis XIII or XIV style.
The Barbizon is another revival frame, made popular in the 19th Century and inspired by the much earlier Louis XIII and XIV frame patterns. These Barbizon styles are quite common in many museums and art galleries, often framing many different 19th Century artists and modern masters. This frame is just having some minor repairs.
