Cooey Model 840 Serial Number Lookup ((hot)) [2025]

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.

Summary for Identification

If you are looking at your serial number: Cooey Model 840 Serial Number Lookup

  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)

How to "Look Up" Your Cooey 840

Because no official database exists, the lookup process is more art than science. Here’s your roadmap:

  1. The Physical Inspection (Do this first): The Collector’s Guide: Cooey Model 840 Serial Number

    • No number? You have a pre-1968 classic. Congratulations—that is your lookup result.
    • A number present? Write it down. Note its location (left receiver, under the woodline, on the barrel near the breech).

  2. Check the Barrel Stamp (The Real Clue):

    • Ignore the serial for a moment. Look at the barrel’s left side, near the receiver. You’ll see patent numbers and proof marks.
    • A stamp reading "Cooey Model 840" with a small "W" in a circle indicates a Winchester-era gun (post-1965).
    • A stamp reading "H.W. Cooey Machine & Arms Co." is a pre-1965 Canadian original.

  3. Use the "Cross-Model" Clues:

    • The 840 is mechanically identical to the Cooey Model 39 (single-shot) and the Model 60 (repeater). Many 840s are actually re-branded 60s. Look for a tiny "60" stamped under the stock line—if you find it, your "840" is a late-model rebadge from the early 1970s.

  4. The Canadian Gun Forum Deep Dive:

    • The only real "database" exists in the collective memory of forums like CanadianGunNutz.com. Post a photo of your markings there. Expect replies like: "Ah, the 'A' prefix with the serifed font—that’s Cobourg, third shift, 1971. I’d bet my toque on it."

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. Here is the next best thing to a serial number lookup. Smooth, uncheckered hardwood: WWII-era guns (wood was cheap
