I do hope they produce an accurate jacket. My comment was objective and factual. Two panel Irvins were used in 1939 and 1940 and only from 1941 did the four panel jackets start to get produced in large numbers. Therefore to call a four panel Irvin a Battle of Britain jacket is incorrect and they have done this their website for years. Perhaps they will change the title when the new jackets are produced? I like being pedantic about the historical accuracy of jackets-its stems from my training as a historian!
