Description
By 1880, Keuffel & Esser was offering a "Y Level, Telescope 18–20 inch long, magnifying power 22 times, best make, guaranteed, in mahogany case, with Tripod complete" for $140. But since Keuffel & Esser did not begin manufacturing surveying instruments until 1885, these early K&E instruments were probably made by others.This example is marked "Keuffel & Esser New York 303" and probably dates from around 1885.
