Hell yeah!!

The bar on the left hand side indicates a cavalry carbine, also the thumb-lock on the breech-block is MkII or MkIII. the MkIs were converted from the Enfield muzzle-loader and nick-named 'suicide-breech' because of the lack of locking device, as in the one pictured above.

Sniders are never marked as such on the actual firearm. They just are!

You have an interesting historical rifle there, dcmbsn, though they can be a challenge to load for. Visit the Snider/Enfield pages on the British Militaria Forums for more info.

Hope this helps.
