Canadian Indian Gift rifle and back action locks?

Here is a link to a percussion trade gift rifle from the Canadian Government it seems, second rifle in picture with the back action lock.

Here is another forum thread.

Interested if anyone knows much about these rifles? There seems a connection to using recycled Baker barrels. I like the Canadian connection and the stock shape mirroring a military shape.

Also interested in general info on back action locks?

Thanks for the link. I like his nontypical view.

There are a number interesting features and it might make for a nice tribute wannabe copy Trade Rifle.

Folks list pros and cons for the back action lock but it was used extensively in the late percussion era. The weakened inletting for the wrist is worth considering yet many back action guns have survived well. Also the lockswere quite often used in the cartridge era, some searching revealed superb H&H back action shotgun locks on doubles. The narrow side lock region of the stock profile appeals most to me. There is talk of larger wrists with back actions though. The round reused barrel and stock profile make for an interesting transition gun of sorts.

The full length stock with stock wedges and hook breech are a plus for ease of cleaning like my Investarm Hawkens look-a-likes are. There is also a chance they were supplied after Confederation, 1867, making them true trade rifles from the Dominion of Canada.

There is a copy of an article from another of my forums.
