Serial numbers were not required on long arms before Jan 1, 1969. Most manufacturers did not assign serial numbers to small caliber rifles or utility shotguns.
Various versions of the 94 were made from 1926 to 1945. Stevens serial numbers were repeated, so exact dating is impossible.
Most all Stevens 9478 models were made between 1978-1985
Your stevens model 9478 shotgun was made during the years 1978-1985.while serial numbers were on the shotguns I do not believe that serial number records were kept as to the year of production.
If it was manufactured before 1968 it probably doesn't have one.
