This is a Leica screw mount lens. It's a very short Elmar with a lens barrel number of 3. It's a pre-war nickel-plated version with no serial number. Please check the images for the exterior condition. There are signs of use appropriate for its age. Inside the lens, there is some dust and debris, but no mold or mold marks. When held up to strong light, there is a slight haze, but considering its age, it's still in good condition. If you are concerned, please consider an overhaul. The collapsing mechanism is smooth, and the focusing ring moves smoothly throughout its range. The aperture lever has been adjusted to be quite light, making it easier to use. Also included is the original lens hood. It has a rare specification with a nickel-plated tip knob, an aluminum hood tip, and a brass black paint base. This alone is worth 10,000 to 20,000 yen. This item is warped and doesn't fit well, but there was no vignetting in actual shooting. Please use it as a practical item. Everything in the images is included. Please understand that this is a used item before purchasing.
