Cooey Model 840 Serial Number Lookup: A Collector’s Guide If you’ve inherited a rugged single-shot shotgun or found a deal on a "Made in Canada" classic, chances are you’re holding a Cooey Model 840. These firearms are staples of Canadian hunting history, known for their simple break-action design and reliability.

However, if you are trying to perform a Cooey Model 840 serial number lookup, you’ve likely run into a common frustration: many of these guns don't have serial numbers at all. Here is everything you need to know about dating your Model 840 and understanding its history. The Short Answer: Why You Can’t Find a Serial Number

Before 1968, firearm regulations in Canada and the United States did not strictly require serial numbers on rimfire rifles or shotguns. Since the Cooey Model 840 was designed as an affordable, utility firearm, the H.W. Cooey Machine & Arms Company (and later Winchester-Western) often omitted them to keep production costs low.

If your barrel and receiver are blank, don't worry—your gun isn't "missing" its ID; it simply never had one. Identifying the Era of Your Cooey 840

Since a standard serial number database doesn’t exist for most Cooeys, collectors use rollmarks (the stamps on the barrel) to narrow down the manufacturing date. 1. The Winchester Era (Post-1961)

Occasionally, you will find a small letter stamped near the breech or on the trigger guard. While not a serial number, these are often factory proof marks. While there is no definitive public ledger for these codes, they generally signify the inspector or the specific assembly line. Why the Model 840 is Special

Even without a serial number to track its exact "birthday," the Model 840 is highly regarded for its:

Versatility: It was chambered in 12, 16, 20, and 28 gauge, as well as .410 bore. Durability: The action is famously overbuilt.

Automatic Ejectors: Unlike many budget single-shots, the 840 is known for its strong ejection, snapping spent shells well clear of the shooter. How to Value a Cooey 840 Without a Serial Number

Since you can't use a serial number to prove "rarity," value is based entirely on condition and gauge:

Common Gauges (12 & 20): Typically sell for $150 – $250 CAD depending on wood condition and bore brightness.

Rare Gauges (.410 & 28ga): These are highly sought after by collectors and can fetch $300 – $500+ CAD.

Condition: Check for "case coloring" on the receiver. If the rainbow-like finish is still vivid, the value increases significantly. Final Tips for Owners

The Collector’s Guide: Cooey Model 840 Serial Number Lookup and Dating

For generations of Canadian shooters, hunters, and trappers, the name "Cooey" represents rugged reliability and affordability. Among the most iconic of these firearms is the Cooey Model 840, a bolt-action shotgun that has served as a first gun for countless outdoorsmen. Whether you inherited one from your grandfather or picked one up at a rural auction, understanding its history often starts with one question: How do I perform a Cooey Model 840 serial number lookup?

Unlike modern firearms manufactured by mega-corporations like Winchester or Remington, dating a Cooey is not a straightforward, database-driven process. This article will explain everything you need to know about the serial numbering system (or lack thereof), how to identify your specific model variation, and where to find the hidden markings on your barrel and receiver.

🧠 Fun Fact for Collectors

The Cooey 840 is sometimes called “the farmer’s gun”—it lived in barns, pickup trucks, and traplines for decades. Low serial numbers? Rare. But a well-worn 840 with no number? That’s actually more original.

The Late-Bloomer Numbers (Post-1968)

Things get interesting in late 1968. New gun laws required serialization. Cooey (then owned by Winchester-Western) reluctantly complied. On these late-production Model 840s, you’ll find a serial number—usually on the left side of the receiver or the trigger guard.

But here’s the catch: Cooey’s serial numbers were chaotic. There is no known, comprehensive factory ledger. They often used batch codes, inspector stamps, or Winchester-era numbering systems that overlap confusingly with the Cooey Model 60 and 600.

For example, a typical late 840 serial might look like A12345. What does the "A" mean? Possibly a production shift, a subcontractor batch, or a Tuesday morning run in Cobourg. Nobody knows for sure.

Summary for Identification

If you are looking at your serial number:

  1. If there is no serial number, it is likely Pre-1960s.
  2. If it has a serial number, look for the "Winchester" logo. If present, it is Post-1961.
  3. If the proof marks are on the barrel near the receiver and the address is "Winchester, Ontario," it is a classic era (1948–1961)

Step 1: Physically Locating the Markings

For a proper "Cooey Model 840 serial number lookup," your first step is to put away your magnifying glass and search the gun itself. Here is where to look:

  1. The Left Side of the Barrel: Near the breech (where the barrel meets the receiver), you will find the factory stampings. Typical markings include:

    • Cooey Model 840
    • .410 Bore (or 20 Gauge)
    • Cobourg, Ont. (or later, Winchester-Western, New Haven, Conn.)

  2. The Underside of the Barrel: Remove the barrel from the stock (the Model 840 has a simple takedown screw on the forend). On the underside of the barrel, near the chamber, you may find small stamped letters or numbers. These are often "fitting codes" or inspection stamps (e.g., a circle with "WP" for Winchester proof), not true serial numbers.

  3. The Receiver Wall: If a serial number exists, it will be on the left side of the receiver, often just above the trigger guard or behind the bolt handle cutout. If the metal is smooth here, you have a pre-1961 gun with no serial number.
