I admit that talking about the "Battle of Britain" and a "1945 pattern" seems slightly whimsical.
However, I think to split hairs, 70 years hence, between September 1940 and early 1941 is just a little pedantic.
If they are making an effort to produce an accurate jacket - and they appear to be trying, can't we wait until it appears before critiquing it?
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!
