Very interesting. Thanks Guys.
So, the question then becomes - when did Turnbull get his last 2 kills? Shores in the Spearman edition of Aces High simply states he shot down a Zero on 19/3 and got 2 more before the squadron withdrew to the mainland. (I only just became aware the Grub St edition of Aces High has much better detail - have ordered one)
