Hibbard Spencer Bartlett & Co sold guns with the Newport name as early as the 1880s, but a hammerless Newport double would have been made by either Crescent between 1903 and 1930 or Stevens after that. The HSB trade names were discontinued during or shortly after World War 2.
Do you mean a hammerless single-shot, double-barrel, slide-action...? sales@countrygunsmith.net

No published sn data.
It sounds to me like you have a Early made Ithaca Baker model double barrel shotgun made in 1889-1890.As to value I would have someone with the knowledge to evaluate you gun and then he could assign a value for you.
Made for Sears Roebuck by Stevens. There may be a model number on the right side of the receiver (most likely 5000, 5100, or 311) or a Sears product number on the barrel (101.6?) which could give an approximate date.
The gauge is stamped on the water table by the serial number. It is a Flues model made in 1924.
Made in 1901
Open the action and on the receiver flat will be the serial number and another number denoting the grade. Need all of that information, as well as some digital pictures to determine condition. sales@countrygunsmith.net
