Well, bear in mind that I may be misremembering about the hoof marking. She may be NC, I can't get to her to check at the moment and I don't have a photo of her hooves. So don't mark it down yet, not until I can verify.
I bought her in 2016, apparently. And I thought I found a picture but turned out that was a different pony from someone else. This is the problem I have with a large collection of donated MIP images
.
I'll keep looking and let you know. It would probably be quicker to take the cupboard apart but I am not quite sure which part of the shelf she's on.
Final edit - I gave up with the photos and put a torch in the cupboard. The pony fairies are shining on you as I could actually see her xD. She is NC. You can breathe again. My bad
