1961 Valiant Wagon

Any knowledge on 60/61 Heater hose markings would be great. I got this a fair while ago now. I am unsure if its Australian or North American (I just cant remember). I don't really see the DPCD logo used on printed items in Australia...Only on North American mopars. This hose has no ribbing which is common for Australian pieces. Most Heater hoses from North America have ribbing. Any Thoughts ??
