     Its likely all these are originally from the Library of 
Congress archives.  There are a great many WW-II vintage 
photographs there including a very large number of 
Kodachromes.  Other sites often take the TIFF files and 
process them in an image editor like Photoshop or Gimp 
(freeware) to correct the color.  At the LOC site photos are 
available as moderate sized JPG or very large TIFF files.
     The Kodachrome of the period had a speed equivalent to 
about ISO-12 for the daylight types and a bit faster for the 
tungsten type, maybe as fast as EI-25. Grainless, brilliant 
color, and excellent dark storage were characteristics.
    The disadvantage of Kodachrome was the extremely complex 
processing method.  All sheet film had to be processed at 
Kodak in Rochester, N.Y., 35mm still film and motion picture 
film was also processed in Los Angeles and in Chicago 
although I am not certain of the date the Chicago plant was 
established.
