Just be sure to keep the original stock around with the - 342,7xx would probably be 1933. The Z stamp is just an inspection stamp at that time, it has no correlation to dates.
Here is a complete list of the Lever Boss Codes and their corresponding year of manufacture: A= 1949 B= 1950 C= 1951 D= 1952 E= 1953 F= 1954 G= 1955 H= 1956 I= 1957 J= 1958 K= 1959 L= 1960 M= 1961 N= 1962 O= SKIPPED P=1963 Q= SKIPPED R= 1964 S= 1965 T= 1966 U= 1967 V= 1968 W= 1969 X= 1970I believe the extended action was not released until 1957 and the tang safety was started in 1964 Hi Rick, Thanks again for the info. I think I'm going to need an electron-microsope to see the letter. The “lever boss” is the extension of the lower part of the receiver into which the lever fits and rotates. t=304218In 1949, Savage began stamping a tiny, lightly impressed oval on the lower, front side of the "lever boss".WE dont shoot it that often though because ammo is expensive.Anyhow, the serial number is 646346 and it doesnt have a letter in it. If the serial number is over 500,000 or starts with an A then a 6H would mean that inspector #6 did a final inspection of the rifle in 1956.Your specimen without a serial number was made before January 1, 1969.There are no records to give a more exact date, however Savage has a date code system.The Savage/Stevens date code is a 1/4" diameter circle located on the receiver or the barrel which contains one or two numbers and a letter.The letter is the date code which began in 1949; A = 1949, B = 1950, C = 1951, D = 1952, etc.Specifically, 1,06x,xxx serial numbers would be 1963. Has anyone ever seen a lever boss stamped with a cloverleaf?
