Mowrey's had good barrels, and incredibly simple locks, that functioned well. They were a copy of the Allen&Thurber late percussion box lock rifle. They made a couple of models, one in a plains rifle caliber, and a smaller version in Squirrel cablers. They all had curly maple stocks. The steel action is preferable, since the steel tumbler would wear the brass action, and require bushing to cure binding, over time. They also made a Hawken, but I've never seen one.
I owned a Mowrey in .45 Cal., years ago. It was one of their squirrel models. It shot very well, and for a single trigger, had a smooth trigger pull.
