Do you know how old i am?

I don't have a history at all on this. I am trying to find out exactly the date of this model from Seth Thomas. Believe it or not a little old lady gave it to me and I have had it for twenty years. Just saw it sitting in the cabinet and wondered about the history. I know its Seth Thomas and I know it is an 8 day (?). It has felt on the bottom and is extremely heavy. It still works when you turn. Would love to know more about it. There is NO other Seth Thomas pictures like this one on the internet. Not that I could find.
