Rare vintage Nikon zoom lens. 15 elements in 8 groups; 28-1/2 to 10 degrees angle of view; focusses to 4m; and has a Series IX accessory size. Glass is clean, except for one small spec on the corner. Very close to the edge. Pretty sure it's outside frame area.
Comes with Nikon adapter but should fit other systems with proper adapter. Lens hood included and a front removable glass element. Not sure what it is. The flaking paint is on the front adapter, not on the lens.
