Up for sale is a used, manual focus Bell & Howell / Angenieux 3" (75mm) f/2.5 C-mount tele prime lens, serial #397185, which comes with its original metal screw-on front cap but no rear cap.  The lens is in usable shape in its current state, but would definitely benefit from a CLA so it is being sold for repair.  There is some fairly heavy internal haze towards the front of the lens and there may be some spots of internal fungus as well.  Note, however, how different the glass looks when harshly lit from both the front and rear when the angle of the flashlight is changed just a bit (see photos 8-11).  Additionally, although focusing is not stiff, it is a bit uneven across the range (it's not terrible, but it's also not silky smooth the way it should be).  Aperture adjustment is smooth, but there is a bit of oil residue on the blades.  Cosmetically, the barrel exhibits minor overall wear from previous use.  Please be sure to fully enlarge the provided photos, and feel free to contact me with any questions you may have.
