Here are a few pix of Grandpa's gun...I hope they are attached!

I found this web site, http://www.savage99.com/savage99_dates.htm, which actually made me more confused. It gave me two different dates of manufacture, 1946 or 1918 according to American Rifleman.

Then it said the Lever Boss code of C, gives me a date of 1951.
Is that C in my pictures, the lever boss?
