The Cooey model 84 (later renamed the model 840) was the first shotgun designed and manufactured by the H. W. Cooey Machine & Arms Company in Coburg, Ontario, Canada. It was sold as the model 84 until 1967, and (following acquisition by Olin Corp.) as model 840. The gun, along with all other Cooey products, ceased production in 1979.
Contrary to information given on another wiki, these are not collector's items, unless you can pick up one of the rare ones chambered for 28 gauge or with a 36" barrel. As for the rest, they are one of the most (if not the most) ubiquitous shotguns in Canada - everybody and their dog has one.
Guns made prior to 1961 will be stamped "H. W. Cooey Machine & Arms Company" on the right side of the receiver and those made after Olin's acquisition of Cooey will instead be stamped "Winchester-Western (Canada) Limited." They came with barrels 26", 28" and 30" in length, with 32", 34" being much more uncommon and 36" downright rare. The most common choke in an original barrel was full choke, which is the most desirable configuration when a tight pattern is needed.
The model 84/840 comes chambered for most common shotgun shells including 12, 16, 20 and (very rarely) 28 gauge, as well as .410 bore. A new owner should get the chamber measured for the proper size of shotshell by a gunsmith since most of the older 84s were chambered for 2 3/4" shotshells (except .410s), while the 840s were chambered for the larger and more powerful 3" shotshells.
There were not many documents kept on the production history of Cooey firearms in the first place, and fewer still survive to the present day. Written records of serial numbers are therefore not generally available. Some have suggested that Cooey did not use serial numbers at all prior to being bought out by Olin, and many model 84 / 840 units manufactured prior to 1970 do not, in fact, have serial numbers. On the other hand, there are also many pre-1961 model 84s which are stamped with serial numbers on the receiver (directly beneath the branding), barrel (under the forend stock) and under the butt plate/shoulder stock. Dating the serial numbers remains a challenge (to put it nicely) for Cooey gun collectors.
At about the same time, Winchester "introduced" the same damn shotgun as the Winchester Model 370. After the Coburg plant closed, Winchester dropped the Winchester Cooey Model 840 and did a little upgrade work to the outside of the Model 370, calling it the Winchester Model 37A.
Cooey manufactured 221,578 Model 370s from 1968-73 and 395,168 37A units from 1973-79.
