In the late '40s or early '50s there was a series of articles showing how to "sporterize" the Springfield in the "American Rifleman". The series ran for three issures if memory serves and showed a cut down military stock as the first option, the second option was to turn the stock from the pistol grip back into a dowel, bore a hole in a matching piece of walnut for the butstock, glue over the dowel remnant of the original stock and then shape as desired. The final option was to restock the action.
It appears that this stock was done in a similair manner.
