Here it is - the lens is so old that I needed 2 adapters to get it to work - it is a very early 16mm lens - and has what Kodak called an S-Mount. Later video/cinema cameras went to a standard mount called the C-Mount. So, I have a S-Mount to C-Mount adapter and from there a C-Mount to Micro 4/3 to adapt it to my camera body. These lens are so old that quite often the focus is stuck because the grease hardens - this one luckily still has the focus and the aperture working pretty smoothly.
This was in my office wall when the sunlight penetrated the beveled glass of my side door early in the morning.
