RRA= Rock River Arsenal? Don't know what the CSA is unless it's inspector's initials -- I doubt that it means Confederate States of America. Not on an WW2 gun!
A great many M-1 carbines were rebuilt at the end of WW2. Although many probably needed it, they also had changes that were done. A adjustable rear sight replaced a "L" shaped flip rear sight and a front barrel-band with a bayonet lug were two items that were added during the final months of WW2.
Also a round bolt replaced a flat-top type. Not all carbines received all these new parts.
I have a 1944 marked Inland trhat has the early flip "L" type rear sight and the type 2 barrel band without the bayonet lug and the flat top bolt.
Nice gun by the way.
