It looks as if a couple of the forum brothers have answered the specific question, but I would also recommend the book, The Fusil de Tulle in New France 1691-1741, by Russel Bouchard. Track of the Wolf has it for $16.95, which is a lot for a small book (essentially a 48-page pamphlet), but there is a lot of information in there, including an excellent chapter about the early French long guns. The illustrations are all black and white, but are remarkably clear, including detail photos (inside and out) of a 1697 French lock. There are numerous professionally drafted pen-and-ink drawings also, and in my opinion these are sometimes better than photographs.
I would also recommend T.M Hamilton's Colonial Frontier Guns, available from Track for $17.95. There is quite a lot about early French guns in this book, although I find it a little disorganized.
The Bouchard book is focused entirely on French guns. The Hamilton book has a mix of nationalities and focuses on trade guns. The Gale book has the best pictures, in color, and the text gives precise measurements of every gun. You can get both the Bouchard and the Hamilton books for a little less than For Trade and Treaty, but if there is any way you can afford it, I would recommend all three. I have all three and find them all to be excellent references.
The definitive reference on French trade guns, as far as I know, is The French Trade Gun in North America 1662- 1759, by Kevin Gladysz. It was only in print for a very short time, and apparently in a limited run. I missed the opportunity to get a copy when they were available new, and used copies now start at around $300. More than I want to pay. However, you might check with your local library and see if they can get a copy via interlibrary loan.
Bonne chance! I hope you find what you need.
