My Winchester 94 30-30 has a serial number of 4756906. How can you tell what year it was manufactured?

your winchester was made in 1978,,current value for a post 64 winchester would range between 250 good -400 excellent,,dealers will proably offer between 125-200 depending on condition ,,many books are available and the one i use the most for serial number data is the blue book of gun values..
