Oddly its not a list I have - I think mainly due to a distinct lack of information on them. However, I would ponder how often the same pony got the same brush as the ones I have seen are different from those BFB has seen - I had a Blossom with her white flower brush and a friend still has a Cotton Candy with a purple flower brush and a Windy with a purple star brush [2 of these match the original pony and 1 of them doesnt]
Apologies for adding to the confusion.
