If you have the most common, a standard sporting rifle, one of the most popular cartridges, and NRA Very Good condition (95% of the original finish and all original parts). For guns made before 1964, all models (rifle, carbine, trapper's carbine) are close to the same value for the basic gun without special features EXCEPT the "Eastern" carbines nade without a saddle ring from 1940-1964, which are much less.
When a value is quoted, it is usually from one of the standard books, but books don't buy guns. The true value is the amount a willing seller will accept from a willing buyer. Of course, one reason a gun could bring more than the guide books suggest is some documented association with a famous person or event. If you can prove it once belonged to Buffalo Bill or one of the original Texas Rangers, there is no established value guide. Even a connection to a Texas law enforcement officer in the 1900-1930 period would add a significant amount. I am looking into the serial number for better dating...
It appears that your gun was only made in 1964. As far as a value goes, I am having trouble getting an exact figure on this, due to my membership problem with Orion BlueBooks (Gun Value)

Or, If you have the lists in something like the Blue Book of Gun Values. It can be found at most any book store, and ordered online.
You can also try a Web site such as Savage Arms or oldguns.net.
Or, you may try contacting Browning on their 800 number with the serial number of your Winchester. (Winchester firearms is now owned by Browning.) They can confirm with you when it was made.
I am still looking for a value for you but still having trouble. If the question closes before I find you a value, I will send you a private message.
