Vintage Carl Zeiss Jena lens. Looking for a super fast sharp wet plate lens?...165mm  focal length, fast  f2.7 !!! Glass is very clean. Aperture works great. I originally purchased to shoot flash w wet plate but never got there. Has built in flange ready to mount. Glass has some light dust and tiny bubbles but nothing that will affect image.   apeture is f2.7 - f32   has built in mounting flange . Lens hole size for lens board is 3 - 1/8 inch diameter. Flange diameter from mounting screws is aprox
3 - 5/8 inch. Body shows normal wear for its age.. See pics. Awesome rare fast vintage lens. Covers atleast 4x5 at infinity, close to 5x7.  Would be great for wet plate to speed up exposures or  use flash.  serial # 785323  dates this lens at 1924
