martini henry rifles

[Jack]

There is a thriving cottage industry in that area of making fakes of some of the typical rifles used in that region in the past. Including the Martini actioned rifles, and even Lee Enfields.
I believe American Rifleman has written about the fakes in the past.
As best I can recall, some of the fakes are amazingly good copies, but, since they are done under primitive conditions, the fakes have no heat treating at all, and are made with whatever metal was handy.
In other words, they aren't something you would want to shoot. If you're after a souvenir to hang on the wall, they might be interesting.
Unless one of the experts here can tell you how to tell real from copies, I would be very, very wary.
