The pickups are little odd. Usually, the Seth Lover set has a smooth base plate, a sticker in the middle with a rubber stamp serial number, and the blue "Seth E Lover / Seymour Duncan" signature stamp over it. Then there's the little model number and date sticker by the leg.
If you look at the photos here at Sweetwater, they have an image of a 2016 Seth Lover

Usually what they look like.
Looks like you have a bridge with the embossed "Seymour Duncan" logo pressed into it, no rubber-stamp sticker and no blue signature. But the neck (fuzzy background) looks more like I'd expect.
I think the H-535 '06 is actually "106". Which makes sense if it was part of special run or something.
Perhaps the internal sticker has been lost to the winds. It is just a paper decal, a dose of humidity or bad luck might loosen it. Or someone picked it out, or who knows on a 9-year old guitar.
I think you got one someone's mildly modified.
The blonde 2001 with HRW pickups I own, I found a couple of years ago at a shop that had it marked as a 2020 for some weird reason. It was pristine, with the original Schaller hardware. It had "the sound" one wants from a 535. Had to have it. I later found it had the waviest fretboard to escape the factory. Neck perfectly straight, fretboard like a roller-coaster, though all the frets were level. Some were brand new tall, and some were leveled down to .027" tall. Eventually I pulled all the frets, leveled the rosewood, then refretted it myself with medium jumbo, which means the nibs had to go, then put Faber hardware. So, the moral of that story is you never know what someone does to them in the field.
What counts is how good it is.
My 98 H150 I bought used when it was 2-3 years old, from the original selling dealer. (Buffalo Brothers, who were a big Heritage dealer long ago). They ordered the run with this spec, and took this one back in trade from the original purchaser. The SD59's in it are OEM ones that SD sold to manufacturers back then. No stickers and a little different stamping on the back. So definitely original.
