L. Hitchcock ladies writing desk and chair

L. Hitchcock desk and chair. It was my wife's grandmother's and has been in the family since it was bought new, although I can't seem to get that info. The chair is in good shape but the desk is starting to chip paint and could use a good cleaning. I can find any markings on the desk like the one the chair has. Looking to know anything about the set and how much it is worth.
