I would like to add to my reference library more information about AF O gauge as I often run into these items when acquiring Lionel collections. I have catalogs for 1938 and 1939. IF I were to buy AF catalogs for two years between 1930 and 1937, what tow years migth give me the widest spread of information on locomotives and cars ? Same question for three years. I'd get them all, but that's too costly.
