Emil Busch Rathenow Neokino 52.5 / 95mm (f/1.8) projection lens 350858
The glass is beautifully clean and in excellent condition. It's ready to go and will produce or project great images from the start. The barrel is not so good with some wear and dirt (see photos). I don't quite understand the numbers on the lens but if "52.5" is the glass diameter then that is a speed of f/1.8 though this is not stated. The barrel is 2" (52mm). No iris or other moving parts.
