If the model number isn't marked somewhere on the gun, it's pretty hard to determine exactly which Stevens double you have since they made at least 60 different models in three basic configurations - side hammer, back hammer, and hammerless. I can tell you that the "arms & tool" version of the company name was used from 1886 to 1916. If has a hammerless boxlock action, it was made after 1903.
