Plenty of fake CRK's out there. Mostly seem to be fake Sebenzas, not sure about the Pacific.
I've linked below to the Pacific on CRK's website. On there, there are markings on both sides. The CRK logo and Harsey signature on one side and Idaho Made on the other.
On the one that you photographed, there's a lack of coating. The finger guard contours look rounded rather than slightly angular. The serrations look different and are longer and more spread out.

I'm not an expert so it could just be an older model or it could be fake, don't know.
I'd ask a mod and see if they would move this to the Chris Reeve Forum on here as you will probably get quicker and accurate responses.
