Marble topped end table (Cambridgeport)

This end table (24" x 24" x 20" high) belonged to my grandparents, probably acquired 1950's or 1960's. The top is marble and is actually not attached, but is heavy enough to stay in place. One of the door handles is broken off, so those would need to be replaced. There seems to be some stains on the finish on the sides, so some sort of refinishing or repainting might be in order. The under side of the marble top is stenciled with "ART Product MADE IN ITALY".
