Chainring is correct, it's 49t with no space for the cutout. I've never seen a 00 in square and the internet doesn't help dating it either. But can't be 2000 as it's not the modern branded version, but a second generation with engraved logo.
Yeah i've definately seen this chainring with this version crankset before. I was under the impression that it's a v3 though. I believe v2 is the same lasered logo but further up the arm.
