In the year 1949,Winchester produced 126,100 rifles and carbines to catch up with demand that had built up during the World War II years.As far as collectors are concerned 1894 Winchesters made from 1940-1960 will bring a 50% premium for those chambered in 25-35Win.That being said I can only assume that this caliber only represents 10% of total production,which in your case means 1949 saw 12,600 so chambered.
