That appears to be the same badge as is on my 2015 Copperphonic...in other words the current Ludwig keystone re-issue. Also a vintage KB drum would have a brass grommet not a silver one. So the badge dates from the past 3-4 years. That doesn't necessarily indicate the age of the drum if it's not the original badge (although I'm unsure how someone from outside the factory could lay their hands on one of these new badges. Drum companies tend to try to prevent those getting out).
So I don't know what drum you may have...but that isn't a pre-serial keystone badge, circa 1960-1963.
