I think the nosecap stamp is a crown with BP or BR under it then a number, if its BP, going to get a magnifine glass later and reinspect, but if its a BP that would match the knox form marking, and it has 2 /l\ markings, one on the bayonet lug and one on the front face of the cap. The /l\ logo is also on the Buttplate, which i swapped from the one stock to the other. I honestly have several buttstocks, one with "AA" carved initials in it, it looks to be a little different in the fact that the lower grip is rounded off where most come to a point where ones pinky finger rests, there is not notches cut out for a safety on the top front and the few markings on it in the lower front of the buttstock are not discernible, the seem to be full of grime ad oil and blurry tot he eye, perhaps there is a stripper or something which can safely lift it all out? I will post a picture of it this evening.
