I found a Stevens single shot 12g, hammerless, gun with a ribbed barrel...the first 5 inches of barrel is octagon, stock and forearm are very checkered an also has an auto-ejector. No model or identity marks anywhere except for the Stevens label on one side of the action. Almost has the look of a Model 94. Serial # 110 but I can't match that to my serial number dbase.
Any ideas what this is?

Thanks
