Taylor-Hobson Cooke anastigmat 15mm f2.5 c-mount 215501 cine lens

If anything is a 'pancake lens', it must be this! A sweet little Cooke 15mm movie lens. Fixed focus. Stops down to f/16. Glass is in good condition, barrel has some normal wear, commensurate with its age, 1920s I think, so from the earliest days of 16mm cinematography. Comes with modern metal rear cap.
