Roll crimp and Tapered crimp

Can the forum provide picture examples of a roll crimp and a tapered crimp?

On a rolled crimp the end of the case is rolled over sligthly into the bullet to form the crimp. Revolver bullets seat on the case rim. On a taper the case is flattened onto the sides of the bullet so that the edge of the case is squared off. Pistol bullets seat on the squared edge of the taper crimp.
