The Stevens date code usually appears on the bottom of the frame behind the hinge pin. I dont believe the marks you have on the water table are the date codes. The Z was not used, the (A) is 1949 and the (I) is 1957, but these usually have numbers in the circle with them. sales@countrygunsmith.net

Pull down on forearm. It should come off. Then break open shotgun, barrels should hinge off.
Does it say J. Stevens AND Co or J. Stevens ARMS & TOOL Co or J. Stevens ARMS Co? The first would have been made from 1865 to 1886, the second from 1886 to 1915, and the third from 1920 to about 1945 (unlikely if it has damascus barrels). Value is $100 - $300 depending on condition, but only as a mantle decoration. Damascus or twist barrels were fine when they were produced, but were not intended for modern smokeless ammunition. Even if they were proofed for smokeless powder circa 1900, today's smokeless is not the same and after a century the barrels have probably deteriorated.
