Hello, I got these great chairs and having a hard time finding the line name? they are stamped Drexel with original tags. The legs are different from anything Im finding. They are not marked Heritage, so I believe that is before 1963? or 53? covers must have been redone cos the stapling is sloppy! Like to also know if they would be worth having them refinished, there is some damage on one of the legs. just chunk missing.
