I'm pretty certain that's not Kell's work. Dealers use Kell's name on English gamescenes the way they use Del Greco (mispelled, I know) on Parkers.
Most likely, a guy by the last name of Brown did the work on it, or at least some of it. I bet one person did the game scenes and another did the scroll.
Brown also engraved the Thousand Dollar Grade Lefevers (or Lefever, I don't know how many $1000-grades were made).
Scott made a lot more than 50 Premiers, too. I think they offered them for over 60 years, so there must be hundreds of them out there. I've seen a lot of them.
Now this is a really rare Scott:
