I can't say who made the Mountain Rifle. It was NOT Lyman! Lyman does NOT make ANY guns. They merely import them. Usually from Spain & Italy. But at the time Browning was selling those rifles, they were having a number of their rifles made in Japan. Probably still are. That rifle MIGHT have been made by B.C. Miroku. If so, it is of higher quality than most of the Spanish ones, and probably as good as those of Italian origin.....
