The Cooey Model 840, produced between 1967 and 1979 by Winchester-Western (Canada), lacks a public, detailed serial number database for precise dating.

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. A Brief History of the Cooey 840 Before diving into the serial number lookup, it’s critical to understand the manufacturer’s timeline. The Cooey Machine & Arms Company was founded in 1919 by John Cooey in Cobourg, Ontario. The Model 840 was introduced in the late 1930s as an improvement over the earlier single-shot models (like the Model 39 and 84). The Model 840 is a single-shot, bolt-action .410 bore shotgun (though rare 20-gauge versions exist). It is famous for its "snap-action" bolt release and lightweight design. Production continued through World War II and into the post-war era until 1961, when Cooey was purchased by Olin Industries—the parent company of Winchester-Western. Crucial Fact for Your Lookup: Prior to the Winchester acquisition in 1961, most Cooey firearms did not have a serial number. Canadian law did not require serial numbers on low-cost utility firearms for decades. If your Cooey 840 has a serial number, it was likely manufactured after 1961, or it was an export model to the United States (where serialization became mandatory under the 1968 Gun Control Act). 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:

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 Serial Number Lookup

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

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.

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. The Cooey Model 840 was produced between 1967 and 1979

Step 2: Decoding What You Find Because a comprehensive Cooey Model 840 serial number lookup database does not exist online or via government registries (the Canadian Firearms Registry was destroyed in 2012), you must use indirect methods to date your gun. Scenario A: No Serial Number Found If your receiver has no number, your shotgun was manufactured between 1938 and 1961 in Cobourg, Ontario. These are the most common versions. You can narrow down the era by examining the extractor and bolt handle:

Early 840s (1938-1945): Feature a round, smooth bolt handle and a small extractor. Late 840s (1946-1961): Feature a fluted bolt handle and a larger extractor.

Scenario B: A Serial Number Exists (Usually 5 or 6 digits) If you find a number on the receiver, you likely have a late-production Model 840. There are two sub-scenarios: Dating is primarily determined by physical markers, such

Made in Cobourg but Serialized (Rare, ~1960-1961): As Cooey anticipated new regulations, they began adding numbers to some models. These numbers are typically low (e.g., 1000 to 15000) and stamped in a small font. Made in New Haven, Connecticut (Post-1961): After Winchester took over, production moved to the US. These guns are marked "Winchester-Western" on the barrel. Their serial numbers follow Winchester’s internal system. However, Winchester kept producing the Cooey 840 as a budget gun until the early 1970s. Very few of these exist.

Scenario C: "Import" Markings If your gun has a serial number on the barrel but also says "Made in Canada" with an importer's stamp (e.g., "O.F. Mossberg & Sons"), it was an American-export model from the 1960s. In this case, the serial number is purely for US GCA 1968 compliance and offers no date. Step 3: Using Alternative Dating Methods (Since a Serial Number Lookup Fails) Since you cannot simply type a number into a government database for a Cooey 840, you must rely on batch codes and physical features .
