Marlin Serial Number Lookup
Enter a Marlin serial number to estimate the year it was made — using an author's published transcription of Marlin manufacturing-date prefix codes. It is an explicit first–last serial range, model by model and year by year (0 documented ranges, –): your serial is matched against the interval Marlin published for it, never guessed. Every result cites the chart row it came from. Marlin stamps its date as a prefix at the head of the serial, not as serial ranges: a single letter 1945–1968 where case is part of the code (C = 1945, small c = 1946), then two-digit prefixes 1968–2011, then MR = 2011. Enter the serial exactly as stamped — the capitalisation of the first letters changes the answer.
Enter the number exactly as stamped — including any letter prefix.

Most serial charts give one number per year. Marlin is different, and using the wrong method gives the wrong year — so it is worth knowing what the chart actually asserts.
An explicit serial range per model and year
for every charted model year the published chart gives the first and last serial number of each year, for example a bracketed interval per year. That is the most precise form of this data: your serial is not merely compared against a boundary, it falls inside a documented interval. Where two published ranges overlap, the tool gives you the span rather than picking one.
1945–2011 — the serial prefix itself is the year code
Marlin did not publish serial-range charts; it stamped a date-code prefix on the serial. From 1945 to 1968 the prefix is a single letter, and the published chart distinguishes case: capital letters come first (C = 1945), small letters continue the count (small c = 1946). B is printed with no year — the WWII gap — and is refused here, not guessed. From 1968 the prefix is two digits counting the years down across the eight-digit serials (68 = 1968 … 89 = 2011), and MR marks the 2011 series applied at the Remington plant after Sturm-Ruger acquired Marlin.
Pre-1941 Marlins carry no date code at all, so a pre-1941 serial gets an honest refusal here, not a false year.
Which Marlin models this covers
The published chart covers 0 models across 0 ranges, and every one of them is listed on this page. There is no model beyond this table with data to search.
If your model is not listed, the published chart we hold does not cover it — the tool will say so rather than guess.
Published Marlin serial ranges
0 documented ranges across 0 models, from an author's published transcription of Marlin manufacturing-date prefix codes. Transcribed one row per chart section, exactly as published — the coverage note above states what is not here.

Questions
Why does my serial number not give a year?
It falls in a gap between the published ranges, or in a model year the chart does not cover — the tool will show the nearest documented range instead of guessing. A public lookup should not invent an answer. For a Marlin: a pre-1941 serial carries no code; B is printed without a year (WWII gap); a prefix the chart does not print is refused. None of these is rounded to a neighbouring year.
How accurate is this?
The ranges are reproduced exactly as published in an author's published transcription of Marlin manufacturing-date prefix codes. That is not a factory letter — for a definitive date, the factory records are the authority. The prefix decoder is derived from an author's published chart (leeroysramblings.com), not a maker page. The numeric era is verified against the chart's own worked example; the letter era carries the chart's published self-contradiction, surfaced with every affected answer. No prefix is ever extrapolated beyond what the chart prints.
Where does the data come from?
the manufacturer-date-code chart published at leeroysramblings.com — An author's published Marlin date-code chart (leeroysramblings.com) — not a maker-published page. The chart contradicts itself in one place (the grid prints N = 1956 while the surrounding text says 1955): the tool shows the grid value and states the disagreement, it never picks silently. The source also notes MR-prefixed serials were applied in 2011 at the Remington plant, which the tool reports with its answer.
Records & archives
A chart says what the factory serials mean. Our records note for Marlin says who actually holds the factory records today, whether a letter of authenticity can be ordered, and what it costs and takes — observed, not assumed.
