This is a .243 Winchester Featherweight barrel. The manufacturing date is not legible; it may be 1953. It has the number 5 front sight ramp, indicating it was probably manufactured around 1954. The #5 ramp was only used for a short period of time and Roger Rule describes it as "experimental" in his book The Rifleman's Rifle.
