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)
The Model 840 was actually a transition model produced after Winchester-Western (Canada) Ltd. purchased Cooey in 1961. Unlike the earlier Model 84, the 840 features a more modern aesthetic, often with a square-shaped forearm.
Check the Barrel: Look for the text "Winchester-Western (Canada) Limited." If this is present, your gun was made between 1967 and 1979 at the Cobourg, Ontario plant.
The "Winchester 370" Connection: The Model 840 is virtually identical to the Winchester Model 370. If your 840 has a serial number, it was likely produced toward the end of the production run (late 70s) when numbering became more standardized for export. 2. Proof Marks and Letters
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. Cooey Model 840 Serial Number Lookup
Condition: Check for "case coloring" on the receiver. If the rainbow-like finish is still vivid, the value increases significantly. Final Tips for Owners
If you are recording the firearm for insurance purposes or your PAL (Possession and Acquisition License) records and there is no serial number, simply list it as "NSN" (No Serial Number). This is a standard and legal designation for vintage firearms of this era.
The Cooey Model 840 may not have a digital paper trail, but it carries a massive legacy. Whether it’s a family heirloom or a bush gun, it remains a functional piece of North American firearm history.
Are you looking to refinish the wood or find replacement parts like a firing pin for your 840?
The cellar smelled of damp earth and old oil, the unmistakable perfume of a estate sale cleanup. Elias pushed aside a stack of warped National Geographic magazines to reveal the prize: a battered gun case.
"Find anything good?" called out his business partner, Sarah, from the top of the stairs.
"Maybe," Elias muttered, unzipping the canvas. Inside lay a pump-action shotgun. It was utilitarian, lacking the high-gloss finish of modern firearms, but it had a certain rugged charm. The wood was dark with age, the bluing on the barrel worn to a soft grey.
Elias racked the action. Clack-clack. It was smooth. Too smooth for a gun that looked this rough.
He turned the firearm over, looking for the maker’s mark. On the receiver, faint but legible: COOEY. And beneath it, the model number: 840.
"It's a Cooey," Elias shouted up. "Model 840. Canadian made. Probably mid-century."
" worth anything?"
"It depends," Elias said, pulling a penlight from his pocket. He tilted the barrel toward the light, searching for the string of digits that dictated whether this was a fifty-dollar wall-hanger or a rare collectible.
He found it stamped near the receiver. The serial number was faint, obscured by a layer of cosmoline and surface rust. He squinted, wiping it gently with his thumb.
F 12784.
Elias climbed the stairs, the shotgun broken down over his shoulder. "I need to run a lookup. Cooeys are tricky. They were the working man’s gun. A lot of them didn't even have serial numbers until the late sixties. If this one has one, and if it’s a low number or a specific prefix, it could tell us exactly when it left the factory in Cobourg, Ontario."
Back at the office, Elias sat in front of his dual-monitor setup. The Cooey Model 840 was a staple of Canadian hunting camps for decades—simple, reliable, and affordable. But information on specific production runs was notoriously scarce. Unlike Winchester or Remington, which had meticulous ledgers, Cooey records were spotty.
He navigated to a specialized firearms archive forum, a digital backroom where collectors traded scans of old catalogs and shipping manifests. He typed into the search bar: Cooey Model 840 Serial Number Lookup.
The results were a mess of conflicting data. He clicked on a sticky thread titled "The Great Cooey Database Project."
Elias rubbed his temples. The internet was a labyrinth. He needed a concrete reference. He pulled a heavy, binder-clipped book from the shelf behind him: The Collector's Guide to Canadian Arms.
He flipped to the section on the H.W. Cooey Machine & Tool Company. There was a chart, hand-drawn by a historian in the 90s. It listed the prefix codes. Whether you are trying to sell, insure, or
The entry for 'F' stopped him cold. There was an asterisk.
Note: The 'F' prefix was not a standard chronological run. It was allocated to a special contract in 1964, two years after Winchester acquired the company. These were "transition" guns—Cooey actions stamped with the standalone name, but built with higher-grade Winchester steel specs for a government contract (Department of Lands and Forests).
Elias looked at the number again. F 12784.
He cross-referenced the number on a database maintained by a collector in Alberta. He typed in the prefix and the digits. The server chugged.
Result found.
Serial: F 12784 Shipped: November 12, 1964 Destination: Northern Service Depot, Thompson, Manitoba. Notes: "Winter Issue" - Chrome bolt, modified stock for cold weather gloves.
"Sarah," Elias said, his voice dropping to a whisper. "Look at this."
Sarah rolled her chair over. "What is it?"
"It's not just a shop gun," Elias said. "This wasn't sold in a hardware store. It was a government contract shotgun. This was likely issued to a game warden or a surveyor in Northern Manitoba. That explains the smooth action—it wasn't used by a weekend hunter; it was maintained by a professional who needed it to work at forty below zero."
He scrolled down further. A user had uploaded a photo of a similar 'F' series gun. The description detailed a recall that happened in 1965. A batch of the wood used for the stocks had a defect—it was prone to cracking at the wrist if not properly oiled.
Elias turned the gun over and looked at the wrist of the stock, where the neck met the receiver. It looked pristine. But he took a magnifying glass to it.
There it was. A hairline fracture, expertly repaired with period-correct epoxy. Someone had loved this gun. Someone had fixed it.
"So?" Sarah asked. "Is it worth millions?"
"No," Elias smiled, closing the book. "It's worth about three hundred dollars to a collector. But the story is worth more."
He looked at the scarred wood and the faint serial number. The lookup hadn't just given him a date; it had given the gun a past. It had sat in a cabin in Thompson, Manitoba. It had survived a recall. It had been carried by someone who worked the traplines or the forests.
"Label it," Sarah said, standing up. "Put it on the site for four hundred. Tell the story about the Northern Service Depot."
Elias nodded, but he hesitated before typing the listing. He ran his hand down the barrel.
"Actually," he said. "I think I'll keep this one."
"Why?"
"Because," Elias said, opening the database tab one last time to screenshot the serial number lookup for his personal file, "it feels like it still has some work to do." Elias rubbed his temples
