Victorian Brass and Leather Bound Three Draw Field Telescope

Here is a good probably mid Victorian in date brass and leather bound three draw field telescope, there is no makers mark that I can find, the optics are very good and you can focus it easily, it comes in fair condition with cosmetic issues, the main bottom barrel has three dents, this has no effect on its performance, some of the leather shows signs of age and use but it comes complete with its top and bottom lense covers, the lenses themselves could do with a clean. It measures 11 inches closed and 29 fully extended.
