If memory serves me correctly were not those early 311s made under the Lewis patent sold under the Springfield name rather than Stevens.
I had one of these many years ago but it was "Badged" as a Central Arms Co name. It was a 28" barreled 20 gauge but weighed a full 7 lbs. Even though I could shoot it reasonably well I sent it on down the road, as I felt if I were going to carry a 7 lb gun it may as well be a 12.
