Bardou Refracting Telescope

Maison Bardou, for many years a leading manufacturer of small telescopes for education and recreation, was established in Paris in 1818. The firm displayed their wares at the Centennial Exhibition in Philadelphia in 1876.
This telescope has a brass tube assembly marked "A. BARDOU PARIS," an objective lens of 3½ inch aperture and 52 inch focus, and a wooden tripod. The signature indicates that it was made around between 1878 and 1895. James W. Queen & Co., the leading purveyor of scientific instruments in the United States, offered similar instruments for $175.
Everett Harrington Hurlburt, later to become a professional astronomer and physicist, received this from his father in the early 1920s. He continued to use it throughout his life, particularly for viewing solar eclipses.
