These French gun canes came in cartridge and percussion. They were used to capitalize on the popularity of dart blow guns during the victorian era. I've always wanted to shoot one just to know how much of a kick there is on the teeth. This one is 32 cal. You can see the air hole below the handle and about half way down where it screws open to put the cartridge. This one has its original shell remover attached to the ferrule. Stepped malacca shaft. As gun canes go a 2 rarity and a D value. I'd call this average condition.
