How would we know it was a specific make/model bomb that exploded? I doubt there'd be a "W88 Copy" label thrown clear and found in the rubble.

We would know from the massive yield that a W88 produces (500kt) compared to a backpack nuke (under 1 kt) or a Pakistani nuke (40 kt)

Why would one use a missile warhead design for delivery via a shipping container? I would think that a special design with higher yield, perhaps 5 Mtons, would work better -- particularly because the "circular error probability" of a container delivery is greater than a missle. You also need to make sure it is designed to not be detected by radiation monitors.
