There are actually 3-4 different TP or DP '93's. I used to go through hundreds, if not thousands, looking for the different types. Whenever I saw the closely spaced digits, I always had to have a good 2nd look. We only put 1 D/P in the 2011 Charlton due to space limitations.
I have 30 DP & TP '93's and about 1/3 of them also have the 3 repunched. Here are a few of them from years ago on my binocs. By the way, I always considered the first 9 photo here to be quad-punched 9 ... count the strikes.
