Picked up a Keysone (by the inverted K in the cutoff recess) 03A3 stock on the cheap....It's a "porker" C stock, whose only markngs are the "K" and the letters "A O P", spaced where the inspector/arsenal cartouche goes...Curious regarding the meaning of those.....Some previous owner had sanded the wrist, apparently had small hands....I do too, so this one will be a shooter.....Still curious.....Thanks in advance
