I once had a 20ga version of this Stevens 315 marked as a Central Arms Co. One thing Researcher didn't make really clear here, likely just assuming we all knew it, The Stevens 311 & associated models are fired by a rotating hammer, & not the spring loaded striker as in the 315 model. At the same time I had the striker fired Central Arms Co gun my Dad had a 16ga Eastern Arms Co one which was hammer fired. Both guns had a very similar shaped frame & looked very much alike. One difference of note is the location of the two cross pins through the rear of the frame. On the striker fired guns the rear pin is higher in the frame than is the forward one while on the hammer fired guns the rear pin is lower, very near the frame bottom.
