No such caliber as .32 Special. Use the caliber of ammo marked on the gun.

Impossible to answer without knowing who made it.
.380 is slightly larger in diamater than the .32, and in general, more powerful.
If it's a 1863 model then it would be a cap and ball model, not cartridge, and it would be about a 31 or 36 caliber. However, if the piece was converted to cartridge then it COULD be a 32 cal. cartridge.
