This spyglass measures 17 inches long when all three sections are fully extended.
I've always like these telescopes. They were favorites of sailors and military officers from the Civil War until WWI. This spyglass measures 7 inches closed and 17 inches long when all three sections are fully extended. I believe this instrument is about 100 years old; it's marked "made in France" on the lens cap in letters so small they must be read with a magnifying glass. It has clear optics and will give good service in your home, on your boat, or in the field. And it comes with its own round leather case.
