THIS THREAD shows the roll crimp done to the extreme, but you might be able to get the idea of what you are looking for from it.
The newer black Arc AAAs are roll crimped from the factory, and of course all of the "plain HA III" units produced now are. Unless you have aquired an old pre-V3.1 Arc AAA that hasn't been done by hand, you have a roll crimped Arc AAA.
