You might, and I stress, might be able to get a little information if you post over on winchestercollector.org.
They are being produced.
Winchester produced 720,609 model 1873 rifles between the years 1873-1923.
Winchester did not keep records of the production by year of the model 77,22cal rifles.I can say that the model 77 was made from 1955-1962.Winchester made 217,000 rifles during this time span.I would say that your rifles serial number puts your rifles production in the first year which is 1955.
Yes,these rifles were blued at the factory at the time of production.
The last year of production for the Winchester model 61 was in 1962.They made 10,661 rifles that year.
The first lever action rifle by Winchester was the Henry rifle.It was produced from 1860-1866.
I would place your Winchester model 70 rifles year of production at 1999-2000.
Manufactured before 1968. No serial number was required. Many of Winchester mass produced .22 rifles did not have one.
I assume that you have a model of 1917 enfield made by Winchester.these rifles were made from 1917 to 1919,with a total production of 545,511 rifles made.I am afraid that is the best i can do because Winchester did not have yearly production fiqures available for the war years.
model 190 and model 290 rifles were produced from 1965 to 1980, around 2,171,263 rifles .
If you list your rifles serial number in this question,we can determine the correct year of production for your Winchester model 1892 rifle.
Your Winchester model 1894 rifle was made in the first year of production,which was 1894.During 1894 Winchester made 14,759 rifles of this model.
