She looks like a mink wedge blazed cap stripe(not a complete hood).

And Mark, adding blazes to your breeding colony wouldn't be a good idea. Most can carry the megacolon gene, especially if they are from pet stores and you don't know their background. And that's not something you'd want in your colony. Pet rat breeders have been working VERY diligently to try to eradicate megacolon from any of their animals, breeders or offspring.
