Imagine my disappointment when I mounted my shiny new Wide Angle Dagor and instead of the expected sparkling image, a dull, flat, flared-out low contrast scene appeared. Shot a few negs anyway: sharp but flat. The lens looks good...perfect glass on the outside of the cells. But close inspection with a magnifier in just the right light shows random separation.
American Optical, 3-5/8" f8. Serial no. 759K would put it towards the end of 1937-1945.
Has anyone recemented one of these? It looks as if the optical block would come out from the front, using a rubber grip to unscrew the name ring.
What to expect with separating the elements: Was Goerz still using Canada balsam in the early 1940s?
