Expert Mossberg 590 input required

I have a great curiosity regarding a Mossberg 590 SP shotgun I just purchased NIB from a dealer. It's model # is listed as 50668 on the box, and it's also listed as being parkerized. It's equipped with ghost ring sights, 9-shot tube(8 + 1), and speedfeed stock. It's also got the little tab for a bayonet up front if you're so inclined.

My question for you Mossberg experts, revolves around it's finish, it's been parkerized, the box clearly states the finish as parkerized, I have looked it over and concluded it's parkerized, as has the gunsmith where I bought the big fella from.

The thing is, model # 50668 does not offer parkerizing as an option, not on the Mossberg website, not in the Mossberg catalog. It's simply listed as being available in blue, or mat blue. Yet this gauge is clearly parkerized. In fact, it appears identical in every way to the 590A1 which is parkerized, except for two, those being the plastic trigger guard & safety. Shotgun was manufactured in 09...

Any ideas, or explanations?

I love Mossberg about as much as a fat kid loves cake but they aren't the best at updating their website.

Well, then their not getting around to the catalog either, or for that matter, their customer service reps, who when contacted assured me that it was blued! It's not blued, it's very definitely parkerized...
