Kynoch 32 S&W Blank made in Canada

This is my only Canadian made Kynoch box. It is scarce in Australia but possibly common in USA? I guess it dates from 1970-72 but I cannot translate the date stamp on the flap. The plastic tray and red annulus are typical of Canadian made ammo . White wad. Were other calibres made for Kynoch?

Very cool box & totally new to me, for whatever that’s worth.
