If it is marked with both the Stevens and Savage names and the 311 designation, it was made sometime after 1948. There should be either a letter and number in a circle between the trigger guard and the hinge if made between 1949 and 1968 or a serial number if made after that. The letter codes for 49-68 are A through V, so your Z does not fit in that sequence.
If it's not immediatley apparent, you won't.
First, you will need to know the manufacturer's name, the model or model number, the serial number and condition of the 10 gauge double barrel shotgun before a "worth", can be considered.
It s a Stevens model 311D double barrel shotgun serial number A226687 16 gauge. everything is on the side of the shotgun.
By designer are you asking what Model it is? If so, the Model can be determined by the serial number, which is located on the barrel flats and the forend. You have to take the barrel off the receiver to see them.
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.
A Model 37 is a "pump", so a double barrel could not be a Model 37
Would need the specific model number.
That depends on the maker. Please provide maker and model number
open gun where the barrels latchs,the model numbers will be right there.
