I apologise in advance for being slightly off topic but this thread has had me racking by brain for several days since the mention of 'Blue Nun'. My first reaction when I saw the name but before I read the context was 'that was what my grandfather smoked'. Obviously this was not right and after days of serious head scratching I have come to the conclusion that his pipe tobacco was probably 'Three Nuns'. Can anyone confirm that there used to be a pipe tobacco of this name sold in round screw top tins about three inches in diameter?
