Field Glasses

This is a brass instrument with a black japan finish. The objective lenses are about 40 mm diameter, and the optics are excellent. The “CHEVALIER * PARIS” signature on each eyepiece refers to an optical firm that was begun by Louis Vincent Chevalier in 1765 and still in the business in the late 19th century. The left eye tube is marked “DAY & NIGHT / EXTRA POWER” and the right is marked “ARMY & NAVY / EXTRA POWER.” There is a black leather case.
