The first Model Marlin 39 was made from 1922-1938.There were no Marlin model 39 lever action rifles made in 1900.
All model 39 Marlins were built in the 1922-1938 time frame. A model 39 with S prefix will usually date to the late 1920's. However, model 39a Marlins with S prefix date to 1957. So it depends on which model you have a 39 or 39a.
