I am selling a vintage Eastman Kodak Anastigmat 130mm lens.   I really know nothing about lens, however I found this in a box of stuff.   Here is what I can tell you about this lens.  Looks to be of a brass construction.  There are front and rear lens that thread into the housing.   The outside diameter of the front lens is .985 inches.  The length of the housing with both lens installed is 1.019 inches.  The outside diameter of the rear lens is .907 inches.   There is a flange on the housing that is 1.107 inches.  The front lens inside ring is stamped with the following “ KODAK ANASTIGMAT 130mm     -   No 222262”,  and the outside ring of the front lens is stamped with “ MADE BY EASTMAN KODAK CO  ROCHESTER  N Y  USA”.  It appears to be brass material with a black coating.   Some wear with brass showing through.   

Please look at the pictures as they are of the actual item.   If you have any questions,  please ask and I will do my best to get you an answer

THIS IS A NO RETURN ITEM. 

Thank you jk
