It is good work. Ever looked at anything done on the continent? The highest grade Granger I ever saw was being completed the last time I was in St. Etienne, and the owner had elected not to have the two pieces of burl checkered. Smart man.
That said, it isn't truly great work. Many are the guns from the houses of the best, that don't have truly great work, either.
I would add the woman who does checkering at Ahlman's Custom gun to the list of very good checkering people, Kathy, I think, is her name.
Best,
Ted
