The caseback shot tells it all. Seiko wouldn't have curved the edges on the underside if they intended to fit a shroud. It's just like on the TST. John's work is top notch, but there's no material to work with on those bottom edges.
That's where I'll stop the comparison because, while it's a bit difficult to tell from the pics, there are a few indications that the fit and finish of this doesn't measure up to John's work.
