French trade guns came in various grades and styles. This is one of the cheapest and more common grades that was sent to America and other French colonies. Fusil de Chasse means 'gun for hunting'. All of the originals I have seen were stocked in a light colored hardwood including beech and maple and usually stained. Large quantities of wood were exported to Europe from America during the 18th century since good hardwoods were becoming scarce in Europe. 

The gun pictured below is stocked in walnut with iron mounts. It has also been aged slightly. Iron mounted originals were left with a bright polish, this one has been browned at the customer's request. A sling was also added which was not commonly found on originals.
