French gun terms, translated by a gunsmith
If you collect French doubles or browse French auction listings, you have met the problem: no general dictionary knows that a bascule is an action body, or that the avantage of a stock is its cast. This glossary translates the working vocabulary of the French gun trade, the language of Saint-Étienne and Liège workshops, into English, term by term. It works in both directions.
In French gunmaking vocabulary, bascule means the action body of a break-action gun, longuesse the fore-end, pontet the trigger guard, quadrillage the checkering, and jaspage the colour case-hardening.
