Yeah the bumpers are all different. I have an NC1 and by the looks @HareLaw, you’ve got an NC2?
I agree with @PaleRider. The Bofi one should fit very well. It’s designed for NC2, so you will probs avoid some hassle compared to me. I would spare the extra £30-40.

I’m very happy with it. It does a great job of hiding the back box far better than stock, and it looks far better too. Needs to be paired with a good back box for full effect. Photos below:
