I showed it to NC, but he reckoned it wasn't one of his. The stock is identical to yours, and the Trakker rear sight has been milled out to fit the odd size Tikka dovetail.
It was a step up from .22LR for sure, and with a 30" barrel and a Jackson CG universal trigger, it still shoots extremely well. (although it now has a Sightron....)
