Hello, I have a Winchester 1867 - 1967 Canadian Centennial lever action 30-30. For all purposes, this rifle was manufactured in 1967. HOWERVER, it has only a 4 digit serial number 1432. It has a saddle ring, but it is a long barrel. the rifle is in very good condition, all original, and not modified. I checked the serial number online through Winchester, and their documents state this rifle was manufactured in 1894. the serial number is clean, and shows no sign of wear and there is no sign of other number that have been worn out. Does anyone have any ideas how this could be?
