This is quite the thread....and now I'm going to add my $0.02 to it...
Yes, the WR kit has incised carving, not relief carving. There is absolutely nothing wrong with it and it can be admired for what it is (machine or hand done) and at the price point, I don't think you can get another quality kit with carving. Personally, I like it and I was really looking at a carved WR...thought of doing a cherry version with black aniline dye followed by alkanet root.
If you're wanting a "perfect" recreation of an original (either as it came from the smith's hands or as it looks today), then sure, the incised WR may not be your preferred starting point. If you're a new shooter, shooter on a budget, doing your first kit or someone who can admire a well worked stock (even it if isn't a perfect clone of an original and "only" incised) then the WR provides a beautiful stepping stone into the world of flintlocks with carving work that puts it head and shoulders above the other kits (Traditions and Pedersoli, I'm looking at you here) that you find in the local gun shops.
It may not float your personal boat, but that's fine....there's lots of room in muzzleloading for a wide variety of interests and likes. In my books, I'd like to encourage folks into the sport (shooting sports in general do not seem to be encouraged or even well tolerated these days) rather than see what we do fade into the past.
Myself, even though I drooled over the carved WR, I ended up going with a Colonial for the .58 cal. Even so, I decided to try my hand at some carving too. The plain stock is nice, but I figured it could use a little something to personalize it and add a bit of dressing up (without making a $500 rifle out of a $1000 kit). I certainly have great appreciation for those who can do full relief carving...but I'm not there yet. I did hand carve incised lines (molding lines), as well as a Maltese cross into my patch box lid, and added an inset for a "coin" in the comb, but that was enough of a feat for my first kit. It might not be perfectly period or perfectly matched to my locale, but it looks good to me, is reasonably "in the ballpark" and I'm going to enjoy shooting it for many years to come.
