The mare is by Cassini I out of Inka, a BWP mare. She is a 1997 model.
Here is a video of Cassinus Z, a Cassini I stallion, also a 1997 model. The interesting thing to me is that he is from the same mare line, albeit with another stallion interposed. His grand dam is my mare's dam. To my eye I see a very strong resemblence. What do you think?
Normally, it is hard to see such closely related adults. I was really tickled to run across this 2d video. It really speaks to how that sire stamped his foals at that time in his career (since both my mare and the stallion are '97 models), and how that stallion worked on that mare line.
