The Steinheil Munchen Casca I is a German viewfinder camera introduced in 1948. It has a proprietary bayonet lens mount that is not interchangeable with the Casca II. Shutter speeds range from 1/25 to 1/1000th, plus bulb.
This camera is being sold as-is for decoration - shutter speeds are not firing properly and focusing is very stiff. It comes with a 50mm f2.8 lens and original leather case.
