I have owned three P-64s in .375 and one custom version. ONE of my originals HAD two crossbolts when I bought it andit was an original Winny stock which would not fit the .458WM.
What I found out and I cannot recall how or where as this waa 15 years ago,was that some factory REPLACEMENT stocks came with these and that is how some got into the market. They SHOULD ALL have had them and so should all of the .338WM rifles as they all crack as the five I have had did.
Fine rifles,among the best ever made, but, the stocks were no screaming hell.
