My 69/70 EB-1 has the same "fallen off" logo and crown. I always though someone etched it out to use crown and logo for restoring a more valuable instrument way back when you couldn't get arrested with an EB-1. I kind of like the look and the story behind it so I never had it "filled".
Speaking of that EB-2D, that is the most marvellously still in shape burgundy I've ever seen on an EB-2, mine turned to bronze/brownish long ago (which is still a nice color). My office is very light all year around, a huge window side and it affects the old sparkling finishes quite visibly. My EB Melody Maker was in pretty pristine sparkle red when I got it a few years ago, it's now more lava pearl and will no doubt be bronzish brown in a few years more. Not that I mind.
From the pics, the repair looks well-done and reassuringly stable, they should have just refinned it.
