comment: There is some haze around the third lens element from the front that could not be completely removed by cleaning. There are also cleaning marks on the front element. However, as this is a radioactive lens, we have left it in its original condition without replacing it.
This lens was manufactured in the early 1950s, around 1952. We hope you will appreciate and enjoy the unique character of this vintage lens, including its age, patina, and overall condition, which reflect its many years of history.
