It appears to be a genuine Fender bridge as it "Fender" wherever there's room to fit it. I rather suprised myself when I didn't cock it up and ruin it, which would have pissed me off no end.
I actually purchased the bridge on August 13th but it's taken a while to get here, since then I have also purchased a David Gilmour neckplate, a wiring kit for a Stratocaster, a black scratchplate and a black backplate - only the David Gilmour neckplate has arrived so far.
