I show that the stevens/savage model 520 was made between 1912-1932 with the total production being 191,000 guns.I would feel safe in saying that yours was made in 1912-1913.
All my records indicate that stevens did not make a model 337 shotgun.If your stevens shotgun is marked U337 under the receiver,this would be a serial number,not a model number.
Depends on model and when it was made. I have a Stevens 84-C that has no SN on it.

The stevens model 9478 shotgun was made between 1978-1985.
model 77 does not have a serial number,they were made before serial numbers were required
Mine does not, I'v had it 40+ years
It s a Stevens model 311D double barrel shotgun serial number A226687 16 gauge. everything is on the side of the shotgun.
Check the receiver and barrel.
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 there is no serial number, it is a 1960's model-up to 1968. In 1968 a law was passed requiring all guns to have a serial number.
I can say that the Stevens model 67 was discontinued in the year 1989.
Stevens Model 940c was manufactured between 1961 and 1970. If your shotgun has no serial number then it was made before 1969.
