Your Montgomery Wards model 37 was made for them by the firm Mossberg and Sons.The Mossberg model 30 and your rifle are one and the same.The Model 30 rifle was made between 1933-1935.
I have a Wards Westernfield model 80 that I bought in the mid 90's from a family friend. She was over 90 years old and told me that her husband had bought the rifle new from Wards in 1936. npbanner@sbcglobal.net

The Montgomery Wards Western Field model 46C was made for them buy Mossberg and sons.The Mossberg model 42A and your rifle are one and the same.Mossberg made the model 42A from 1937-1938.
If your rifle is a bolt action with a tubular magazine, it was likely a Mossberg Model 45A, made for Montgomery Wards under their Westernfield label. That rifle was produced for a brief time- 1937-1938.
If your Wards western field is marked M080,then you have a Savage model 29&model 75.The model 29 was made by Savage from 1929-1967.these were a .22cal slide action rifle with a 22 in barrel in a octagon shape until 1940,and round shape after World War II.I believe that these were re introduced in the 1960,s as the Savage model 75.
The Western Field model 36 .22 rifle was a Montgomery Wards branded Mossberg model 10 or Stevens (Savage) model 52b. Both were sold as Western Field model 36s. These date to the mid-1930s.
The stevens model 87 which is what you have was made from 1938-thru the early 1980,s.There were 1.8 million made during this time span.
We can't tell with a model number- then we MAY be able to give you a range of years. Sort of like asking how old is a Ford car.
All of the Wards SB model shotguns in my cross reference have a number with the letters. Please check your model number closely, and repost your question.
