OK as no-ones answered you I'll put my 10 cents worth in.
It must have been produced after the early 1930's as stopper corks were not used prior to that. The label states "Whisky" so it's not Scotch or Irish as it was law to state what the contents were. The markings on the back of the bottle were used in the US and S America where the custom was to leave a bottle on the table and charge you for how much the bottle had gone down. Up until the 1970's nearly everyone in the Scotch Whisky industry used a thin paper label glued to the back of the bottle so I would suggest it's later than that.
The general design of the label is correct with Courage breweries as is the logo but the name Courage as such only began in 1970 and lasted until the mid 80's [takeovers etc]. It may be that this was a publicity item but if it is whisky in the bottle it must be a mix of Scotch, Irish, Canadian etc.
