i was curious about this rifle so i did a quick google search. found this one for sale:
here is the link
there is also some info out there. this was the "best answer" given to someone on Yahoo answers that was looking for info on the same rifle(two years ago):
Your Cooey .22 rifle was manufactured by H. W. Cooey Machine & Arms Company LTD, Cobourg, Ontario-Canada between 1903-1961 (Before Serial numbers were required/used)
In the Fall of 1961 Cooey was sold to the Olin Corporation, and placed under the supervision of Winchester's Western Production Division (Canada) who in turn produced the Cooey designed rifles well into the Mid 1970's. It was never produced by Marlin or sold under the "Glenfield" brand..
These rifles have no real collectors value but are known to be excellent "shooters" with a value of $75-$150 depending on overall condition and the rifle being 100% unaltered "original" condition.
NOTE* The Marlin Model 60 came later ...
