A friend just picked up a Winchester 1894 in .30 WCF. It's a take-down rifle made in 1897. 90% or better. It has a small, approx. 3 inch handle at the front of the tubular magazine, just under the muzzle. Any idea why? I was thinking it might be some type of primitive lock-out feature. Owner was also thinking about shooting it. I suggested black powder or cowboy action loads. Other info would also be welcomed. Comments.
