Undaunted: Battle of Britain

I seem to be a serial collector of the Undaunted series of games (although I must confess getting them to the table top has been more of a challenge) as I cannot resist their production quality and 'Boys Own' appeal (see below, when I saw the cover of the box art, I knew they already "had me"): 

Perhaps something to be unwrapped (who am I kidding it is already unwrapped) but even perhaps "played" at the weekend sir?
