Wow, such excitement over different views or usages of words.
Though many consider me bull headed, I can defer when presented with new data that refutes or doesn't jibe with the limited info I have. I think most reading this agree that in general, Euro walnut is a pretty common to predominant wood for English guns of the flintlock and percussion period, that there are/were exceptions, and now we know that in some periods it was faddish to use maple, whereas in other periods it was used more sparingly. Cool to know new stuff! I like the burl type stocks myself but wonder if it's possible to plane them.
My previous utterations were a knee jerk reaction to one of my pet peeves, which is the numerous kits out there (from certain suppliers NOT others) for every type of Euro flintlock gun (musket, fusil, fowling piece, trade gun) offered with maple as the primary wood. Not the first time I've made sweeping, inaccurate statements.
Nor the first time when I've been corrected (even better).
