The catalog numbers don't seem to correlate with years other than the higher the number the later the catalog. Up to around WWI the catalogs changed only when something new was to be added. Most were not dated. Sometimes only a supplement or price sheet was added. I keep my catalogs in clear sleeves with a date sticker in the corner. Several have had dates changed many times as I find more on the subject.
More on this subject was added to the posting ".410 barrel for Savage 99"
