This Gundlach-Manhattan Turner-Reich Anastigmat 18'' f/6.8 lens is a series II No. 4. It comes in a Keystone Flashmeter shutter. VSSoutlet staff tests and inspects everything we sell. The results of this testing are: The lens glass is in excellent condition. The shutter sounds fairly accurate - particularly at the faster speeds. There is no fungus, haze or separation to its glass and there is no oil on its aperture blades. The original front lens cap is included. The barrel has some brassing on its high points and edges. There are some minor dust specks inside of the lens. This lens is an excellent choice for large format cameras.
