When SRS was available online in 2004 I got a hit on M1903 serial No. 197478 (I have the RIA rifle with this number). Here is the information provided in the SRS entry: "197478 - - 072306 - RIA INTERCHANGABILTY TEST -"

The listing was in the middle of several similar entries. The question I have was this referring to the RIA or SA serial number. Was it the RIA or SA rifle that was involved with the test?

Of course I wanted it to refer to the RIA rifle, but it occurs to me that it may have referred to the SA rifle of the same serial number. If the "072306" is the date of the entry then I assume it refers to the RIA rifle.
