- This is a brass instrument with a worn black japan finish. The objective lenses are 5 cm (2 inch) diameter, and the optics are very good. The “H. SANDERS MONTREAL” signature on both eye cups refers to Henry Sanders, a late 19th century dealer of optical and scientific instruments.
- The “U.S. NAVY / R 11462” mark on one barrel means that this instrument was used during World War I. So too does the accompanying certificate signed by F.D. Roosevelt, Assistant Secretary of the Navy, acknowledging John W. Cooper’s loan of these glasses to the Navy at that time.
