The Standard Catalog of Firearms has this to say about Stevens SxS shotguns: The firm of J. Stevens produced a number of utility-grade, side-x-side double-barrel shotguns between 1877 and 1988. Not going to copy the whole text. You can read it when you look up your particular model. Stevens guns were always good servicable firearms but nothing fancy. Most are still useable, although any used firearm should be checked by an experienced gunsmith before firing. The earlier models will probably have short chambers and perhaps laminated barrels, and of course, are more likely to be worn.

Since two world wars destroyed many records in Belgium, not much detailed information will be available. Pieper made thousands (maybe millions) of very inexpensive "hardware store guns", a few special-order custom shotguns, and all qualities between.
