Holes Under Butt Plates, Help Needed

[painter777]

Thx Wayne,
It just dawned on me that I have 2 of them (M and Bomb) in the last box at the end of the vault I built. Same box that has the last style HI Type V stocks I have. I posted this picture of 1 back in 09 when I got them. Was the 1st time I'd seen them. You saved me from digging one out. I thank you for that.......
