Browning Superposed History

The production of the Browning Superposed over/under shotgun began in 1931. It has gone through many configurations in the years and is currently still in production through the Browning International Custom Shop.

The information below is critical must have knowledge necessary for ordering parts, wood, and barrels for your Browning Superposed.

What "Configuration Type", "Tang Style", and "Inletting Style" is your Superposed?

  1. Locating your serial number

    The true complete serial number of the Superposed can only be found underneath of the TOP LEVER. All other numbers represent production sequence only and are used by the factory to denote what barrel set is paired with an individual receiver. See figure 1-A to locate the top lever on your firearm.

  2. Reading Your Serial Number

    Below, use the chart to determine the year your Superposed was manufactured.

    Date Historic Information Serial Number Info
    1931-1939 Production of the Superposed 12 ga. began in 1931. 1-17,000
    Exact production figures are not available. Year of manufacture on Pre-World War II production is strictly a guess at best.
    1939-1947 Production ceased during World War II  
    1948   17100-17200
    1949 Production of the 20 ga. began. First series of numbers are for the 12 ga. Second series of numbers are for the 20 ga.
    These serial numbers for each year from 1949-63 are best guess.
    12 ga.: 17201-20000
    20 ga.: 100-1700
    1950   12 ga.: 20001-21000
    20 ga.: 1701-2800
    1951   12 ga.: 21001-27000
    20 ga.: 2801-2100
    1952   12 ga.: 27001-33000
    20 ga.: 3201-5300
    1953   12 ga.: 33001-37000
    20 ga.: 5301-6700
    1954   12 ga.: 37001-43000
    20 ga.: 6701-8400
    1955   12 ga.: 43001-48000
    20 ga.: 8401-9400
    1956   12 ga.: 48001-54000
    20 ga.: 9401-10500
    1957   12 ga.: 54001-59000
    20 ga.: 10501-11500
    1958   12 ga.: 59001-68500
    20 ga.: 11501-14180
    1959   12 ga.: 68501-76500
    20 ga.: 14181-17060
    1960   12 ga.: 76501-86500
    20 ga.: 17061-20640
    1961   12 ga.: 86501-96500
    20 ga.: 20641-23820
    1962   12 ga.: 96501-99999
    20 ga.: 23821-27300
    1963-1968 From 1962 serial numbers were followed by the date of manufacture.
    2S=12 gauge for the year 1962.
    2V=20 gauge for the year 1962.
    2F=28 gauge for the year 1962.
    2J=.410 bore for the year 1962.
    Example: 6556S2 = A 1962 Superposed 12 ga. shotgun with serial number 6556.
    S=12 gauge
    V=20 gauge
    F=28 gauge
    J=.410 bore
    1969-1975 1969 started using two digits for the date of manufacture:
    S=12 gauge
    V=20 gauge
    F=28 gauge
    J=.410 bore
    This was then preceded by the serial number beginning with 1000.
    Example: 1000S69 = A 1969 Superposed 12 ga.. shotgun with a serial number of 1000.
    S=12 gauge
    V=20 gauge
    F=28 gauge
    J=.410 bore

    In 1975 Browning standardized its serial number identification which it followed until 1998.

    1. Superposed Type:
      213=12 gauge
      233=20 gauge
      173=28 gauge
      183=.410 bore
    2. Date of Manufacture is a two digit code:
      Z=1, Y=2, X=3, W=4, V=5, T=6, R=7, P=8, N=9, M=0
    3. Serial Number beginning with 01001 at the start of each year.
    Serial Number Example:


    This would be an Superposed 12 ga., manufactured in 1976 with the serial number 01001.

    Using the above chart you should now be able to distinguish the year and gauge of your Superposed.

  3. Determining Tang Style

    The Browning Superposed was manufactured with 3 "Tang Styles"

    • Straight Tang also know as Superlight
    • Long Tang
    • Short Tang

    Use Figure 1-B to determine the "Tang Style" of your Superposed.

    Figure 1-B

  4. Determining "Inletting" Type

    Two "Inletting" types have been used in the production of Superposed Shotguns.

    • "Y" Inlet
    • "U" Inlet

    Use Figure 1-C to determine what "Inletting" type your Super uses. Most pre 1967 Superposed were manufactured with the "Y" Inletting however, if your Superposed is a 1966, it could be a "Y" or "U" inlet.

With this information, you should be able to correctly identify the most important aspects of your Superposed.
