They came with modified on the right side and full on the left in the 28" and 30" barrels and imp. cyl . and modified in the 26" barrelled models from the factory, from my research, but a lot of owners had them opened up to whatever they wanted, so you have to measure them to be sure.
Measure it, or have a gunsmith measure it, with a choke gauge.
The only info I have on the stevens model 94 shotgun is that it was made between the years 1926-1945.
I have confirmed that the shotgun is indeed a Stevens. Can anyone give me a date of manufacturer based on the above stamping numbers? Serial number lists are not available for Stevens guns, but if you will tell me exactly how the Stevens comapny name is written on the gun, I can give you a general time-period.
1965 if it is an auto-5. There should be markings on barrel to indicate choke.
To determine the choke on a Westernfield Model 155A shotgun, you can look for markings on the barrel, which may indicate the choke type (such as "IC" for Improved Cylinder, "M" for Modified, or "F" for Full). If there are no markings, you can perform a choke gauge test using a choke gauge tool or a caliper to measure the constriction at the muzzle. Alternatively, you can pattern the shotgun using different loads and see how the shot spreads to infer the choke type.
look under the forearm
Complete description and pictures would help, otherwise, can't be done.

The 5100 was made from 1931 to 1941. I didn't know a single trigger was available in the Springfield line. I own an old Springfield double barrel 20 gauge, serial number E67029. Is Springfield the actual model name, I see no reference anywhere to a model 5100. How do I verify what I have. Well, Apollo50, tell us what IS marked on it and maybe we can tell you something.
Take it to a gunsmith and ask him to measure it. He probably won't even charge you for something this simple. If you have a lot of shotguns to check, you can buy a gauge from him. If a dime does not fit down the end of the barral it was full choke. If it is a modified choke a dime will fit inside. Just my 2 cents
