Graf Variable Lens Series A, 11-12.5 inch, f3.8 to 4.5, Serial 5416 $300 + $15 USPS shipping Used this on an 8x10 B&J Grover for portraits. I didn't use the camera movements much. Comes with a lens flange. There's a little dust and slight cleaning marks. The lens was originally mounted on a 6x6 lens board with a with a 4.5-inch No. 6 Packard shutter with a 2.5-inch opening (both available, the shutter has instantaneous but no pin). The lens flange has a small notch in it for the instantaneous pin.
