Information on Gilman Brothers or Jeanne Robinette or Fashioned by Blair

Hi . . . looking for some info on three companies that made porcelain pharmacy items back around 1950. The three companies are Blair (Blair Specialties, Fashioned by Blair), Gilman Brothers, Inc (Boston), and Jeanne Robinette of California. There isn't much about who started the companies, where they were located, when they were in business, what years they made the pharmacy items, and any other information. If you have any info, brochures, advertising material, please let me know. I collect old pharmacy stuff but would really like to know more about these particular companies. The scales picture is all Blair. The two LARGE mortars and pestles (15" high with 19" pestle) are from Gilman Brothers, Inc. And the apothecary jars are all Jeanne Robinette of somewhere in California. Thanks very much!
