I long ago posted a video of a Ed Roman rant where he has 'harvesting' parts (mostly necks) from doner Gibson's by chopping off the bodies with a hand-axe, it was a video about the non-availability of parts to guitar repair shops.
You can get current issue lightly used (basically new) cases from stratosphere, I like the carbon-fiber hp cases, but they don't have those very often, like the circa 2007 black with dark gray interior,
about 10 years ago these fakes with the wonky serial number had flooded the market from Tradetang and Ali*. in addition to the obvious issues they had multi-piece (layered) neck heel and a scarf joint near the headstock both concealed by the paint job, and goofy often non-functional truss rods.
No, it's a Chinese counterfeit,also the serial number has been used before, and an '06 Custom would have a CS prefix on it ( any event that isn't a '01 serial number) as well the other mentioned defects.
