Stock Naim Power Cord?

Good afternoon. I’ve recently moved around a bunch of my gear and now can’t figure out what if any of my generic appearing black cables are original to my Supernait 2. I understand these are preferable, so is there something that would indicate a stock North American Naim power cable vs the other cords I have lying around?

Thanks!

It should be a pretty thick cable with 16AWG conductors. I don’t remember if they all have the same brand, but the one I can easily reach behind the rack says Yong Sheng.

All my stock Naim power cords are 14AWG in the US
