I acquired this at an auction some time ago, but it has been sitting dormant in a dehumidified storage cabinet. I haven't taken any photos with it. The shutter fires at various speeds, from 1/500th of a second to slow speeds. The speeds seem to change accordingly, though accuracy is unknown. The aperture operates smoothly. The lens appears clean. It's a bright F2 lens and comes with the original metal cap. The viewfinder allows for focusing with a split image. However, as it is an old item, I cannot guarantee its functionality. I would appreciate it if someone is willing to purchase it understanding this.
