Up for sale is an Antique Vintage Bausch & Lomb Precision Refractometer Medical Instrument Device. Based on my research I believe this may be from the 1940's or 1950's....it's a fairly rare device from B & L. It's a HEAVY piece of equipment, it weighs approximately 25 pounds & the size is irregular but it's basic measurements are 21" x 15".
