Mentor Goltz & Breutmann Mentorett

{"overview":"The Mentorett is a German-made camera produced by Goltz & Breutmann of Dresden, the Mentor firm active in the early-to-mid twentieth century. Because the data set is so small, what a Mentorett is worth in 2026 depends heavily on condition, completeness and buyer competition on the day; in today's market a clean, fully-working example sells for more than a cosmetically tired one.","buying_guide":"With any pre-war Mentor-branded camera, inspect the shutter for slow or sticky speeds, check bellows (where fitted) for light leaks at the corners, and look for corrosion on metalwork and lens elements for haze or separation.
