I didn't think they striped them.
Looks like they eliminated the front struts on the front fender. That example has the tail only. There should be a fender under there IMHO.
Here is a Roadster to show the mixing and matching they did. Its a 73 signals removed tail and seat added to an 850.

In short, you are getting a bike that folks just simply loved! They mixed matched and altered all forms of Norton to get that look.
You are pretty lucky guy.
