Notes: "This is an early-style K&E 4212 polar planimeter, a model that had a very long run in the K&E catalogs, from 1892 (when it was known as the model 1111) until 1938. When it was first offered, the model 1111 was an upgrade from the model 1110, adding a multiplier disc. The serial number is 736."
