SOLD Attached are several images of the Darlot lens. The 6 inch ruler did not come out too clear, since the flash washed it out. It shows up in one of the images. The lens has markings of "B.F. & Co.", the U.S. importer. The glass is clean and does not have any scratches. It does not have a serial number. I am asking $125. in U.S. dollars, plus shipping. SOLD
