This was what was known as a Zouave carbine. I remember seeing them in the Navy Arms catalog back in the early 1970s. They were simply a shorter Zouave rifle, and were intended as a brush gun. They did something similar with the so-called Buffalo gun, which was simply a sporterized Zouave with a half-stock, a wooden ramrod, and checkering at the wrist and forearm. The Zouave carbine was also used by some skirmishers for competition. They are a handy little gun.
I remember the Buffalo Hunter. Navy Arms Founder Val Forgett took it on Safari to Africa. I even had one but ended up changing my mind and selling it.
I was thinking about using this one for hunting, myself. I wish the barrel had a 1-48 twist like the BH, though.
Thanks!
