200/4 TELYT-V 1682683 (manufactured 1959) mounted as shown in M VISOFLEX II (circa 1960). Lens works great but does have some slight marks, signs of age (very slight fungus due to age). Focus very smooth and apertures fine. Right way round magnifier 4x OTXBO. Screen/mirror has some marks and dust marks, but works OK. Lens is 595g F4-F22 focusing from infinity down to 3m (10ft). Filter size is 58mm (E58). Comes with built-in, telescopic hood and correct push-on Leica cap (approx. 72mm slip-on fit A72). All made in Wetzlar Germany so superb quality. The lens is a 4 element design by Mandler with much improved colour correction. Base and 16466M have tripod bushes for both 1/4 inch and 3/8 inch, so it will fit virtually all tripods and supports.
