Thanks for the replies!
I have no idea where she came from; I found her in a dutch thrift store. I like the idea of a sort of test run. So far she seems to be OOAK anyway, so that is pretty cool.
I found a lot of italian Peachies over the years and they are always a sort of fleshy colour, not pink at all. Italian Cotton Candies I've seen anywhere from bright pink to greenish-white, however they always have pink hair. This pony's hair is more of a peachy colour, and her body doesn't seem to be faded because inside her neck seam it's the same colour. These were all the stamped eyes version btw, the airbrushed eyes are a lot rarer and have their own colour schemes.
