I had heard the the IJ Hercules was for a period "made" in Canada by Cooey, but according to the interweb, more precisely:

"[The] Iver Johnson Hercules was finished and assembled by the Cooey Firearms Company in Cobourg, Ontario, Canada. Cooey had an arrangement with Iver Johnson from about 1932 to at least 1939 to finish guns for the Canadian and British market."

Sounds like an arrangement not unlike the former Ithaca assembly and repair plant in Dunnville, Ontario.
