Antique Brass Brenkert-Detroit Optical Camera Projector Lens Marked 14” As-is. I’m not an expert therefore I took many pictures. Looks like the lenses need to be cleaned and I am sure it’s hardware will need to be cleaned and oiled. I am selling as pictured. The knob does turn and moves the lens up and down. See pictures. Let me know if you need more pictures or have questions. I am not an expert but I will attempt to assist you. Thank you.
