With its solid construction, adjustment dials, and mounting fittings, it appears to have once formed part of a professional optical instrument, possibly for marine, surveying, military, or laboratory use. The interior has a three-lens optical structure. Both the objective and eyepiece ends can be unscrewed, allowing the inner lenses to be accessed for cleaning or maintenance. Visibility through the lens is somewhat unclear, so this piece is best appreciated as an antique scientific instrument, display object, or collector’s item rather than as a fully practical optical device. There is an area on the side brass plate where an inscription, serial number, or maker’s name appears to have been deliberately removed. This gives the piece an intriguing historical character, sometimes seen on decommissioned military or official-use equipment. The telescope has a strong antique presence, with its aged brass, blackened finish, exposed metal fittings, and industrial appearance giving it a distinctive steampunk-like atmosphere. It is in antique condition with a rich aged surface. The brass and blackened painted areas show many signs of long-term use, including scratches, rubbing, paint loss, corrosion with verdigris, and general wear. Visibility through the lens is slightly unclear. Please refer to the photos for details. ※Please be sure to read the【Important Notes】section below before purchasing. Dimensions: approx.
