This telescope spyglass is large coming in at 34 1/2 in Long opened or full extended and then closed it's 15 in. The weight is 2.1 lb so it is a very well made item. It is very difficult to get it lined up to screw onto the final segment and once you get it screwed in when you pulled the other two lengths out it comes undone. I'm certain that a professional would know how to align the two properly and then screw them in properly and I will leave that to that person.

It has the same closing mechanism over the lens and the eyepiece and closing slides that the Spencer Browning and Company use that's why I speculate that it could possibly be produced by Spencer Browning and company but I am not positive. Look up the Spencer Browning and company spyglass that sold on here and you will see that the sliding mechanism is very much the same but it could be from a company that makes the pieces and sends them out to companies to fabricate and then apply to their own telescope. Regardless the pieces old and opens up three tier has the eyepiece cover as well as the end lens cover and it has all the lenses. When you screw the largest piece with the lens onto the other two sliding pieces it is very difficult to get it lined up and I don't want to force anything so I just leave it to the professionals. I just sold the C. Duhamel spyglass and it very well could be from his company out of New Orleans between 1817 and 1870 considering I bought this at the same estate sale as the other spyglass. Thank you very much for looking now I will let artificial intelligence take a whack at it. Take it away ender of worlds;

This antique spyglass, made of brass, was likely used in the US Navy during the Civil War. With a length of 35 inches, it comes with some extras and may have been manufactured by Spencer Browning & Co. This piece is perfect for any maritime collector interested in owning a piece of history.
