According to a book called "Cooey Firearms made in
Canada
" by John Belton, Cooey converted a bunch of surplus Carcanos to sporters. It was sold at Eaton's, and is chambered in 6.5x53.5 Mannlicher Schoenauer. There was a double set trigger, turned down bolt handle, and the Knox should be marked 6.5 mm. The stocks were checkered and refinished.
It was not recommended to use military ammo, and it was recommeded to use ammo made by CIL for Eatons. Apparently a bunch of these failed, so Eaton's was sued and tried to recall them all.
The writer says don't shoot them!
I saw a couple of these at an auction a couple years back, they only sold for about $100, I should have bought one to add to my Cooey collection, but I'm sure I'll run into one again.
