Joe Rinaudo has a shop in Montrose, California, that specializes in
manufacturing antique reproduction lamps.  He has a Fotoplayer he
restored himself along with other mechanical music items of that
period.  Seems like copying Electrova post lamps might be right up
his alley.  Might be worth an inquiry:
