Mike,
Here's what I have so far for photography of your rolled-edge samples.
I labelled your samples A, B, and C, with five inspection sites per sample:
Here are shallow-depth-of-field side views of all sites, with focus on the edge apex. The top row = sample A, middle row = sample B, and bottom row = sample C. In each row, sites 1 to 5 are presented in order, with site 1 at the left and site 5 at the right:
I found sample B to be of the most interest, as the rough texture everywhere on samples A and C made edge details less conspicuous.
For sample B, here are focus-stacked images of the sites seen from the side and seen from above:
Sample B, site 1:
Sample B, site 2:
Sample B, site 3:
Sample B, site 4:
Sample B, site 5:
