You’re right, I never noticed that before and went to google images. This may be the only one with 7 but I can’t tell if the end is a 5 4 or a 5 and 2 other numbers, such crappy tattoos. https://pic8.co/sh/5RC0Ls.jpeg Either way for the Germans being so organized at killing and recording keeping they sure did suck at supposed tattoo numbering. We have 4, 5 and 6 digits, we have a letter then a dash with 3,4,5 and 6 digits. And as this post shows numbering would be dumb in the first place.
