I recently inherited a Stevens, 16 gauge, double barrel shotgun and it doesn't have a model number shown. On the top left barrel is inscribed 16 gauge. On the left side of the shotgun, it has STEVENS, with an engraved picture of a duck or goose flying. On the bottom is, "J. Stevens Arms Company, Chicopee Falls, Mass, USA, Patented April 20, 1915". I'm trying to find out the model number if any and possibly what it is worth. I would rate the shotgun as 85%.
