Finding The History Of Your Classic Shotgun: A Guide To Remington Model 11 48 Serial Number Lookup

The Remington Model 11-48 occupies a unique place in the history of American firearms. As the first of the "New Generation" of semi-automatic shotguns released after World War II, it bridged the gap between the old-school recoil-operated designs and the modern aesthetics we see today. For many owners, discovering the exact age of their heirloom is a point of pride and a necessity for proper maintenance.

Performing a remington model 11 48 serial number lookup is more than just a search for a date; it is a way to connect with the post-war industrial boom of the United States. Whether you have inherited a family piece or found a gem at a local shop, understanding the markings on your shotgun is the first step in preserving its legacy.

In this guide, we will explore the specific methods used to identify the production year of your 11-48, the difference between serial numbers and barrel codes, and why this specific model remains a favorite among vintage shotgun enthusiasts.

Where to Locate the Remington Model 11 48 Serial Number and Markings

When you first begin your remington model 11 48 serial number lookup, you might be surprised by the various markings found on the receiver and the barrel. Unlike modern firearms where information is often consolidated, vintage Remingtons require a bit of "detective work" across different parts of the metalwork.

The primary serial number is typically located on the side of the receiver. For the Model 11-48, this is usually found on the left side of the receiver, near the bottom edge. This number is unique to the frame of the gun and was used by the factory for inventory and shipping records.

However, for those looking to determine the exact month and year of manufacture, the serial number on the receiver is often less helpful than the markings found on the barrel. Remington utilized a specific alphabetic coding system stamped into the steel, which provides the most accurate data for collectors today.

Decoding the Remington Barrel Date Code System (1948–1968)

To successfully complete a remington model 11 48 serial number lookup, you must look at the left side of the barrel, just forward of the receiver. You will likely see a two or three-letter code. This is the Remington Date Code, and it is the "secret key" to unlocking the age of your shotgun.

The first letter in the sequence represents the month of manufacture, while the following letter (or letters) represents the year. Remington used a repeating cycle of letters for months, famously remembered by the mnemonic "BLACKPOWDERX."

The Month Code Breakdown:

B – JanuaryL – FebruaryA – MarchC – AprilK – MayP – JuneO – JulyW – AugustD – SeptemberE – OctoberR – NovemberX – December

By identifying the first letter of the stamp on your barrel, you can immediately narrow down exactly when your Remington 11-48 left the factory floor in Ilion, New York.

Matching the Year Code for the Remington Model 11-48 Production Run

Once you have identified the month letter, the next step in your remington model 11 48 serial number lookup is matching the year letter. Since the Model 11-48 was produced between 1948 and 1968, you only need to look for codes within that specific twenty-year window.

Common year codes for the Model 11-48 include:

48 (1948): Often marked with "TT" or "UU"WW (1950)ZZ (1953)B (1955)G (1960)M (1965)P (1968)

It is important to note that if your barrel has been replaced at any point in the last 70 years, the barrel date code will reflect the age of the barrel, not necessarily the receiver. This is why many collectors cross-reference the barrel code with the receiver serial number ranges to ensure the shotgun is "original" or "period-correct."

Why the Remington 11-48 Design Influences Serial Number Placement

The Remington Model 11-48 was a revolutionary design because it used a long-recoil system similar to the older Model 11, but housed it in a streamlined, "modern" stamped-steel receiver. This transition in manufacturing technology meant that serial numbers were applied differently than they were on the older, machined receivers of the early 1900s.

Because the 11-48 was designed to be more affordable and easier to mass-produce, the serial number stampings are often cleaner and more uniform than those found on pre-war models. This makes the remington model 11 48 serial number lookup process relatively straightforward for the average user, as the numbers are rarely obscured by complex engravings unless you own a "Premier" or "D" grade model.

The streamlined design also allowed Remington to offer the 11-48 in an unprecedented variety of gauges, including 12, 16, 20, 28, and .410 bore. The gauge is usually stamped right next to the model designation on the barrel, which helps further categorize the firearm during your search.

Identifying Rare Variations During Your Serial Number Search

As you perform your remington model 11 48 serial number lookup, keep an eye out for specific prefixes or suffixes attached to the number. These small characters can indicate if your shotgun is a standard field model or a more valuable sub-gauge variant.

For example, the 28 gauge and .410 bore versions of the 11-48 are highly sought after by collectors. These were built on a smaller, scaled-down receiver. If your serial number is accompanied by specific letter suffixes like "F" or "J," it may indicate a specific frame size or a limited production run.

Furthermore, some 11-48s were produced as "Sportsman '48" models. While internally identical to the standard 11-48, the Sportsman version was factory-limited to a three-shot capacity to comply with various hunting regulations of the era. The markings on the receiver will clearly state if it is a "Model 11-48" or a "Sportsman '48," but the serial number lookup process remains the same for both.

The Importance of the "Inspector Marks" Near the Serial Number

In addition to the primary date codes, you may notice small symbols—such as an anchor, a heart, or a triangle—stamped near the serial number or on the lug of the barrel. These are inspector marks.

During the production of the Remington Model 11-48, every major component was checked by a factory quality control officer. These marks don't necessarily help with dating the gun, but they do verify that the firearm passed the rigorous safety standards of the Remington factory.

If you see a "Reproof" mark (often a small "P" in a circle), it indicates the gun was returned to the factory at some point for repair or barrel fitting and was tested again for safety. For those doing a deep dive into remington model 11 48 serial number lookup, these tiny details add a layer of individual history to your specific firearm.

How to Handle Discrepancies in Your Remington 11-48 Lookup

Sometimes, a remington model 11 48 serial number lookup can lead to confusing results. You might find a barrel code that suggests the gun was made in 1952, but a receiver serial number that seems to belong to a later production block.

In the world of vintage shotguns, "parts swapping" was very common. Barrels were often changed to provide different chokes (Full, Modified, or Improved Cylinder) for different hunting seasons. If your barrel code and receiver history don't seem to match, it is likely that the barrel was replaced at some point in its life.

To find the most accurate "birth date" of the frame, many enthusiasts reach out to historical societies or use archived Remington catalogs. While the barrel code is the most common way to date these guns, the receiver serial number remains the legal identifier of the firearm.

Maintaining Your Vintage Remington 11-48 After Identification

Once you have successfully completed your remington model 11 48 serial number lookup and determined the age of your shotgun, it is vital to treat it with the care a vintage machine deserves. Since these guns use a long-recoil system (where the barrel moves backward upon firing), they require specific lubrication and maintenance.

Key maintenance tips for the 11-48:

Check the Friction Piece: Ensure the friction ring and spring are correctly oriented for the loads you are shooting.Clean the Magazine Tube: The barrel slides over the magazine tube; keeping this area clean and lightly oiled is essential for reliable cycling.Inspect the Wood: Many 11-48s feature beautiful American Walnut. Checking for hairline cracks near the receiver can prevent long-term damage to the furniture.

Knowing the age of your gun via a serial number lookup helps you understand which replacement parts might be compatible, as minor internal changes were made throughout the 20-year production run.

Staying Informed on Vintage Firearm Trends and Values

The market for vintage Remington shotguns is always evolving. As more people discover the reliability and classic feel of the Model 11-48, their value—especially in smaller gauges—continues to climb. Staying informed about the history of your specific serial number can help you understand the current market value and the rarity of your piece.

Many owners choose to keep a digital record of their remington model 11 48 serial number lookup results, including photos of the markings and any historical data they find. This documentation is invaluable for insurance purposes and for future generations who may inherit the firearm.

Exploring the history of classic American manufacturing is a rewarding journey. The Model 11-48 is a testament to an era when firearms were built to last a lifetime, and by taking the time to decode its markings, you are ensuring that its story continues to be told.
