I think it's closest to an imported PDF85 with a custom paint job and aftermarket Fluence pups installed. Originally sold for about $800, IIRC. Similar to a USA DF622, but:
The tuning keys are imports, not Sperzels (of course, they could be non-original)
The neck bolt pattern looks like the import version, not the USA made bolt ons. See attachment, and note the spacing between the rightmost bolt and the rest. I tried putting a DF neck on a PDF body once and ran into this difference.
If the neck hadn't been painted over, you could see whether it was flatsawn (import) or quartersawn (USA), and the imports used imported instead of USA Seymour Duncan pickups. There might be further info in the pup cavities or neck pocket if you ever decide to have a peek and any marks weren't painted over, but I couldn't tell you what to look for. Imports also didn't use steel frets, so if you start to see corrosion or wear, there's another clue.
So, it's not a rare custom USA model. Sorry. But it's not the cheapest import, either. It has the vibrato, and the knob layout and battery compartment say it has the piezo pickups in the bridge. Also, it has the ergonomic neck heel, not the squarish one found on the lowest imports. I have a PDF80 and think it's a sweet guitar, but it's odd to shell out the $$ for a custom paint job and Fluence pups at this level. Also, all of the imports with trem and Piezo had flame or quilt veneers, so why paint over that? Still, with the upgrades I'll bet it's a sweet sounding & playing guitar.
As for the serial, imports had a 9 digit serial, which may have been added back when refinishing. I think it does indicate a 2012, and the PDF85 model was made that year. One other note; this shape was referred to as a Dragonfly, a Maxxfly, a DF, or a PDF. It's never been called a Fly, so the graphic wouldn't be factory.
