200 year old chair/unknown origin

There are (2) of these chairs that we own. They are identical except the one not pictured has no seat. The one pictured has a repair at the top, looks like it was broken and then glued. I don't know much at all about these chairs except I believe my parents bought them in London in 1971 or so. It is possible they were bought the following year in Chicago IL. My mother says the dealer told her they were at least 200 years old.
