Answer
Hello Richie Burrow.
  With the information you have given, I would say it is a No. 41 Pocket Pistol. The name and address is in two lines: J. STEVENS ARMS CO.
         CHICOPEE FALLS, MASS. U.S.A.
  This is the information found in the 2010 Standard Catalog of Firearms by Dan Shideler:
This is a single-shot pocket pistol chambered for the .22 and .30 Short cartridges. It has a 3.5" part-octagonal barrel that pivots upward for loading. It features an external hammer and a spur-type trigger It has an iron frame with the firing pin mounted in the recoil shield. It is either blued or nickel-plated, with square-butt walnut grips. There were approximately 90,000 manufactured between 1896 and 1916. The price range is from $135 in Poor condition to $450 in Excellent condition.
  Since Stevens began using the title J. STEVENS ARMS CO. in 1916, your pistol would have been one of the last No.41's manufactured.
  I hope this answers your questions, and thank you for asking for me. Charles Gage
