I recently picked this up because it was cheap and "just for the heck of it". It is a Cooey model 84 in 12 gauge. For those that don't know, Cooey was a Canadian firearms icon from 1919 to 1961 when they sold to Winchester. Pretty much every Canadian farm house back in the day had a Cooey or two by the door. Anyhow, this ole girl has been converted to shoot black powder. I don't know if the adapter is a factory made item or a "custom" made item. It doesn't look like the current ones for sale. I have not tried to remove it. It takes up pretty much all of the chamber. I see the adapters on the market now say for shot only. Well, it's obvious by the sights and the scope mounting rail that this ole girl has likely had its share of slugs or balls or whatever shot down the pipe with black powder. Who knows, maybe it was even shot with smokeless powder. I don't imagine it was any too accurate. The bore is nice and there are no bulges. The choke has been opened to pretty much cylinder. I have a fair collection of various Cooey guns so I thought it would be "cool" to add this "unique" gun to the fray. Since it is of low value, I've been thinking of doing some cosmetic enhancements, just to play around and to add "more character". Maybe a white buttplate spacer or recoil pad, make a horn pistol grip cap, swivels plus I have some varying thickness sheets of copper laying around so maybe I'll make up some designs and practice inletting them into the stock. Maybe some stippling on the forearm because I have no checkering tools. She'll be worthless to anyone else when finished but who cares!
