Ok, mine was teale blue, now this was a couple (?) of years ago, so maybe that's not what it was called in modern history

We lived in Kilmarnock at the time and went into Glasgow to buy it. I thought I wanted the regular beige duffle coat but my Mum, who was always a lot more fashion conscious etc., than I, thought the blue was much better. Needless to say, she was right and when I wore it skating at Ayr Ice Rink it was quite the conversation piece and attracted a bit of attention (especially when worn with a skating skirt of that era).
