1903 NRA sporter

I have a 1903 NRA sporter in excellent original condition ( 43B sight, 8-24 barrel date, electropenciled W3L bolt, serno: 1265159). I have the original star gauge record dated 9/5/24 signed by GC Schnell. My question concerns the stock. It is what appears to be identical to the 1922 M2 stock but with two reinforcing bolts which appear original. It has a raw linseed finish. There is no proof "P" but on the toe in front of the sling swivel is a clearly stamped D28225. The stock, except for the bolts, is a perfect match to my 1922 M2. Other than the stock, this rifle is an easy 98%. Any thoughts would be appreciated.
