This lamp has never been polished or cleaned. It is no less that 60 - 75 years old. The cord appears to have been replaced at some point in time. It is functional.
My mom found this in my great great grandma's chicken coupe. So I know it is at least 45 years old. We got it refinished in about 1993. It does have scuffs on it. I was also told it was made out of solid oak.
