Long time nobody posted anything on this but I came across something interesting. I was looking for an old british army rifle I used once when I was young (about 14-15) and finally found it: it was a Martini-Henry. A .451 inch version that was own by my cousin who still had some ammo for it.
Then I had the surprise to find out that this weapon (actually copies made on the Pakistan-Afghanistan border) are still in use today.
I also found interesting various articles on weapons copied by gunsmith of the Khyber Pass. Plenty of inspiration for T2K, I think.
