Which British smoothbore carbines are known to have been used in the war? I recently picked up a Pattern 1840 Constabulary Carbine here in N. America which is an unexpected find here on this side of the pond, especially not bearing sold out of service marks that were common late 1870s/1880s. I do wonder if this little carbine could be something that was sold to the importers early in the conflict? It's small size would have made it a decent cavalry weapon.
