From the restoration of Charles II to the English throne in 1660. "Field Shooting" became a popular sport among gentry. By the middle of the 18th century the "fowling piece" had developed into a most graceful, slender, and full stocked form. This sporting gun became the pattern for this new class of lightweight military arms. Modifications made were attachment of sling swivels, the cutting back of the end of the forestock so that a small socket bayonet could be accommodated, the adoption of the new "carbine bore of .66 caliber" became standard, and usually an iron rammer instead of a wooden one. The standard barrel of this period was octagon to round with the fowling piece bores ranging from 20g. (.62) to 14g. (.69). Brass mounts were typical, often decorated with military motifs when fitted to the fusils. Some fusils were rifled.

This Officers Fusil by "Twigg" is a very nice example of one of these. It has a small bayonet that fits into the butt stock, which has a buttplate with a trap door. The lock plate measures 5 9/16" x 1 9/16". The throw of the cock is 1 9/16". The barrel is a 42" octagon to round, available in .69 caliber or in 12 gauge.
