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.
i got a 12 gauge king nitro double barrel double triggers and double hammers no serial number on it
It sounds to me that you have a Ithaca Flues model double barrel shotgun.With the serial number that you provided,your shotgun was made by Ithaca in 1917.
Your serial number indicates that you have a Ithaca crass model double,that was made in 1903.
With the serial number that you provided,your Ithaca double barrel shotgun with the damascus barrels was produced in the year 1900.

Serial numbers were not required before 1968. If it has one, check under the forearm, on the barrel and on the action.
