Your Model 81 was halted in the year 2003.I would surmise that Marlin had a new model in the works at the time of the model 81 demise.
I would say that your Marlin model 1894 was probably made in the year 1910.
I can say that your Marlin model 336CS was made in the year 1984.I would look to Marlin,s own website to get any more info on your model of Marlin lever action rifle.
I would date your marlin model 92 to the year 1907.
Cannot find reference to a Model cc 550. Perhaps 650, which would be a Marlin Model 55.
You would have to ask Marlin.
Brophy's book on Marlin Firearms history would be the place to start. I own a model 995, have a copy of the manual.
With the serial number that you provided,I would say that your marlin model 1892 was made in either 1907 or 1908.
No, a Marlin 881 stock cannot fit in a model 81. The stock would fit an 881, not an 81.
I would say that with the serial number provided,your Marlin model 1897 was made in the year 1908-1909.
I would try the marlin firearms web site for a answer to your question.PLese be sure which model marlin you have.
I would say that your marlin was made in 1899 if it is a model 1889,1891,1892,1893,1894,1897.I would say that you would probably have a marlin 1893 even though you do not state this in your question.
