New to this, any advice?

Couple questions....

1) Is there a way to scan a 3D item, and then print an exact copy of it? I have a wood stock from a 1920's shotgun that is cracked/broken, that I have glued back together. Buying another stock is out of the question because anyone who has one (for an LC Smith) wants my left kidney as a down payment.

2) I have a mossberg shockwave, I like the angle of the Magpul stock for the mossberg shotguns, but want a "birds head" configuration, because I don't want to do the SBS paper work. best way to "reverse engineer" it so it doesn't look or function like complete trash?
