270 Winchester is the name of the cartridge your rifle uses. It was first introduced in 1925 for the Winchester Model 54 bolt-action rifle, but other rifles made by Winchester, Remington, Browning, and other manufacturers have been chambered for the same cartridge. So, about all I can say for sure is that your gun is less than 80 years old.
Assuming that you have a Browning safari grade bolt action rifle which is chambered in a standard caliber(270 Win.) the value of your rifle with a original finish between 60%-90% is 550 -1175 dollars.Your 6L prefix to the serial number indicates that your rifle was made by FN of Belguim for Browning in 1966.This was during a time when FN used salt to cure and age the stock wood quickly.This caused the firearms to rust under the stock line!If yours has this problem then the value would be diminished quite a bit,
