The original stock would have been the "S" stock w/o grasping Grooves. A scant could be considered correct as a replacement performed either at field level repair or depot level overhaul/rebuild.

So since this particular rifle is in a "S" stock with the finger grooves, that would indicate some sort of armory rework? Unfortunately the stock has been sanded so there aren't any stamps that I can find at the moment.
