Thanks "lozen", your friend's gun #5594 is now the highest serial number on the list.
Rick, you may be right about the 425 serial range running from 1000 to 6000. In my very first post when I started this topic, I said that I thought the total number produced was about 5000.
According to one post, West's book states that the 425 numbering started at "1". Also, in Sterett's article he quotes a letter from Savage stating that their records show an aggregate total of 11,500 number 15 and 425 rifles produced, but they can not separate them. This info is also in West's book and the Blue Book. So obviously some production records did still exist.
I think the only way to solve this puzzle is to continue to collect the actual serial numbers (and calibers, please) of known 425 series High Power rifles. I know we won't be able to get them all, but if we get enough numbers and could figure out a typical survival rate for a similar low production gun, perhaps we could make an educated estimate.
