Strike doubled.

Yes, it's strike doubling. Sometimes referred to as mechanical doubling. Notice how the doubled area is flat. That's a characteristic that can help you recognize it. It is not considered an error and adds no extra value

I agree with the consensus...machine doubling.... You do pick up the details though, good eye. Cheers, RickO
