JAMIN DARLOT? BRASS PETZVAL PROJECTOR LENS 4X5”, 10X15CM VIEW CAMERA APP.165MM
I recognize in the last picture the firm name Jamin. Where the chip off could be the name Darlot.
It comes into focus at approx. 165mm at infinity. It covers 10x15cm, 4x5” no room to play and with some vignetting. Front and rear elements are 60mm in diameter. Barrel’ diameter is 52mm. Comes with flange. Lens without hood is 120mm tall. It has no Waterhouse slot. Which makes this a projector lens.
Rack & pinion moves smoothly. One screw swapped and two missing at the pinion plate.
The lens cosmetically in very good condition. Barrel shows some signs of prior use. Barrel shows no dings, no dents, minor tarnishing, minor scuff marks. The elements are in very good condition. Shows no cleaning marks, no scratches, no haze, no fungus, no separation. See pictures. Shows no dust particles inside. Comes with flange.
