I am looking for info on a Marlin 30-30 I have but can't make sense of anything I find online.

It's a Marlin model 336CS Micro-Groove Barrel Cal. 30/30 Win. I've entered the serial number on several look up sites but find nada. The rifle was purchased in the late 1980's or early 1990's.

Any help would be great.

Thanks

This is how the date codes work on a Marlin:

The following table can be used to date the year of manufacture of a Marlin 336. It is also valid for determining most other Marlin firearm build dates from 1946 to the present.

Marlin year of manufacture maybe determined from the following table of letter/numeral prefixs to the serial number:

Date Prefix(s)
1946 C
1947 D
1948 E
1949 F
1950 G
1951 H
1952 J
1953 K
1954 L
1955 M
1956 N
1957 P
1958 R
1959 S
1960 T
1961 U
1962 V
1963 W
1964 Y, Z
1965 AA
1966 AB
1967 AC
1968 AD, 68
1969 69
1970 70
1971 71
1972 72
Starting in 1973, the year of manufacture can be determined by subtracting the first two digits of the serial number from 100: Example: SN 2512345 would have been made in 1975 [100 - 25 = 75].
