This is a used condition vintage optical device that was widely used during World War II. It was manufactured by the Swiss company Wild Heerbrugg, which was known for producing high-quality surveying and optical instruments.
The TM2 Rangefinder is a stereoscopic instrument that was designed for accurate distance measurement. It consists of two telescopes mounted side by side, each with a reticle and a range scale. The operator would look through both telescopes and adjust the range scale until the two images overlapped. The range could then be read off the scale, providing an accurate distance measurement.
The TM2 Rangefinder was known for its accuracy and reliability and was used for a variety of applications, including artillery targeting and surveying.
Today, the Wild Heerbrugg 1938 TM2 Swiss Military Rangefinder is considered a collectible item and is highly sought after by military history enthusiasts and collectors of vintage optical instruments.
