Johnny - a lot of early B/O badge drums (mostly the late 60's supra and acro shells) had the vent hole high on the shell because of the center bead. The top part of the then new B/O badges were being hidden under the top hoop. Ludwig's 'cheapo' solution was to cut down a bunch of badges to use on those shells. A lot of those 'cut badges' turn up on very early 70's drums. When the workers badged-up a drum, they just reached into the badge bin and used whatever they came up with. There was no real rhyme or reason to it. That's why out of sequence number series in a lot of the badges almost has no real meaning. Apparently, your drum was made while some of these cut badges still occupied the badge bin and someone slapped it on to a drum with a well centralized vent hole. The cut top really stands out.
Little piece of Ludwig trivia and history. The cut badge has a story.
Best of luck with your sale, beautiful example.
