By the serial number on the rifle.
Model 75 was made from 1931-1961 by Cooey (Canada) and then bought out by Winchester who made them as Model 750s until 1978. If you have no serial number that is due to the change in the Manufacturing laws. 1968 and after should have serial numbers.
I own a Cooey Model 84, serial number 7690 estimated to be manufactured circa 1950. Cooey began making shotguns in 1948.
Well, a model 39 .22 implies to me that it may be a Cooey or Winchester/Cooey. The only thing is Cooey never put serial numbers on their rifles. Winchester did after they bought Cooey around WW II. So therefore I would say post 1964 for your rifle.
Your question has used the serial number of your Winchester,not the Model number.Please include a description of your Winchester along with the model number,and the serial number to get a answer about your Winchester.
