That looks like a newer version of the Mustangs I have. I have 3 that are labled Mustang, and got my kids WM badged hydrostatic version. 2 of the 3 mustangs are the old pill style, ie also bought before the hydro versions came out.
Certainly worth a trip to WM and see how it fits etc, and if you like it....BUY IT!
