hube1236, I'll bet that if you look closely, the marking will actually be "Long
BRANCH," a British arsenal.
If the rear sight is located, not on the barrel, forward of the action, but at the rear of the action, the rifle may well be a No. 4 rifle or No. 5 carbine.
I have no images of these to post, but I'll bet friend
Harley Nolden does.
Best,
Johnny
