Ceramic (looks like wood) Table Lamps (pair)

Do not know much about these lamps except that they were found in a storage locker auction I won recently.  The bases appear to be made of pottery/ceramic.  Bases are 17 1/2 inches tall (not including fixture) and width of base is 7 1/2 inches.  Total height including the fixture is 27 1/2 inches.  I could not find anything like them searching online.  Trying to get an approximate year range of manufacturer, manufacturer, possible value or anything else someone might be able to tell me about them.  There are no markings on either that I see.  Both work and cords appear old. Neither have shades.
