Product Code 059N5Q2?

[Hornet2012]

Hi All
Has anyone come across the Lumia 920 product 059N5Q2?
This is the product code under my sim tray, NCS and Navifirm 2.0+ don't recognise it and there are a couple of obscure web pages that mention it?
Can anyone shed any light on this code?

Thanks.

I took a look and some think it for WP and kinect to work together but that properly just a guess.
