TMTM, there is a local guy who has a similar Supra from the same time frame who brought his into a friend's Drum Shop and when I saw it my first impression was that someone had swapped out the Lugs. After looking at it closely I wasn't so sure considering he said he bought it new like that. Since then I have seen at least one posted on another forum and have heard of a couple of others that the owners stated were special order's, so, while not common, there are others out there. In fact there is a 400 (5 x 14) currently on eBay but won't be there long since it looks like a one day listing and has a Buy It Now for $300, item #260227638960.
1984 was around the time that Selmer was getting ready to move Ludwig to North Carolina and based on what I've seen you never know what you might find on Drums from this time-frame. I do know that Ludwig used the Badge you described on the last Drums manufactured in Chicago and when it comes to Catalog images you can take those with a grain of salt using them only as a rough reference to what the Company may have been sending out to their Dealers. I also would'nt be surprised to hear of other Badges, Chicago large Keystones or Blue & Olive that should have serial numbers but don't. Ludwig, as well as other large manufacturing Companies, had / have a tendency to do things like this, either intentionally or unintentionally, your guess is as good as mine. Because of this I often find myself using the term "It is what it is" because trying to make sense of it all can consume a lot of time with no definitive answer when all is said & done..............
