Clean, ordinary Visoflex and LTM examples typically sell for under £120 at saleroom level, while specialist Leitz sales have seen scarcer variants fetch dramatically more — £1,200 in 2005 and £3,000–£4,000 in 2021–2022 — so condition and exact variant drive the price far more than the headline model name.","buying_guide":"Inspect the long optical barrel carefully for fungus, haze and internal dust, check the aperture blades for oil, and look along the coatings for cleaning marks or separation at element edges.
