The use of different fonts on the barrel flats and watertable is the norm on A.H. Fox Gun Co. guns. Here is a pretty close in time 30-inch AE-Grade 20-gauge, which letters as being ordered "Chamber for 2 3/4 shell" --
and as was the policy at the time has 2 5/8 inch chambers.
It appears to me that Savage lengthened the chambers and reproofed serial number 201403 as was their policy and then did some work on the single trigger. That pin through the trigger plate next to the barrel selector slide isn't on any Fox-Kautzky Single Selective Trigger I own.
