I've never personally seen a Seymour Duncan with the logo offset, but that doesn't mean anything really. If you can unscrew the pickup and take a picture o the baseplate that should give us all he info we need to figure out what kind of pickup it is.
Asked a pretty similar question recently over the customer contact form and this was the answer i got:
If it's labeled Seymour Duncan it is a Seymour Duncan. Duncan designeds are labeled Duncan Designed
Those are Seymour Duncan pickups, made right here in Santa Barbara, CA. We use that logo for some OEM's, but not on any over-the-counter, unless you Shop Floor Custom order it that way.
