Any ideas?

[Richard Lodge]

I acquired this little single action fly reel from an ORCA member who theorizes the Rex B stamping might indicate it was made in France. I know "marque deposee" is trademark in French. And Rex in French (and Latin) means king or monarch. Anyone have more information this maker? Perhaps it's of Canadian manufacturer and not French? Would the letter B mean this is model B or is the name Rex B?
Any information would be appreciated.
