- The Spencer Lens Company introduced its Model 55 in 1914, explaining that this “new and unique instrument” had been produced “in answer to a demand for a binocular microscope with a very large stage and also for a very great range in the distance from the stage at which the objectives may be used.” The new Model 56, moreover, was simply the upper part of Model 55.
- This example of the Model 56 has coarse and fine focus, triple nosepiece, rectangular stage, and wooden box. The inscription reads “SPENCER / BUFFALO / USA.” The 143189 serial number indicates a date around 1938.
