Maybe Rich could shed some more light on this, but I doubt that enough butters were being produced by enough breeders two years ago that a butter could accidentally end up in a ten-lot. It seems more probable to me that you have a yellow creamsicle there. Obviously, there's no way for me to know for certain, but I just wonder about the availability of butter babies on a widespread basis two years ago.
Anyone else have an idea about that question? Rich?
