Thanks for those reference examples. Your photos are great and certainly give me a clear view of the seat stay configuration. I would seem that the men's seat cluster is more comparable to the Oz bike than the completely different design used on your ladies model. I am surprised that the design differs to such an extreme between your bikes in that frame area. Good badge shots, need a better view from the movie to compare.
As far as the brakes go (only shown on the farm ride bike, none shown on the tornado fantasy bike); they would appear to be a much newer add-on cable operated caliper style brake. It is definitely not a roller/rod brake set-up.
