Like the ad states, Remington Model 514 made between 1948 and 1971. This is a No Serial Number rifle. I believe it is prior to 1968 because they did not require serial numbers on rifles till 1968. Please look at the pics! It's not a Bull Barrel! Very nice little gun. I had the stock redone about 20yrs ago. Not interested in trades. Respond with your # and I will call you back! Pick up in Dripping Springs. Price is FIRM.
