The rifles that I study and Collect are the Springfield 1922 series and the 1903 NRA Sporters. I seldom see pretty wood on them because the straight grain is more stable. They were made to be used and accuracy was important. The USMC .22 Springfield in the 1903 S stocks must be the variation least studied and for which there is the least information published. The letter that Cplnorton mentioned is the only thing I am aware of that lends credibility to their existence.
