I got this lens over the summer when I cleaned out a darkroom that was part of a small town Newspaper that was moving into a smaller space. I have searched the web and have found little info on it. Was hoping someone may be able to help me find out more. Attaching photos and a link to a catalog. http://www.piercevaubel.com/cam/catalogs/1910murphylp530.htm. MY best guess its a soft focus portrait lens made by another company for the George Murphy Company. Thanks in advance for any help provided.
