Thousands are now in daily use in medical and general laboratories, also by physicians.” In 1930, the No. 44 was “the most popular of all Spencer microscopes for routine work in the laboratory of the hospital, medical school, or general practitioner.” It was “simple in design and durable in construction,” and “fully meets all standard requirements.”
