It's interesting to note that there are nine Spitfire Is from the first 'K' and second 'N' production series; those delivered to 611 Sqn were:

From http://www.spitfires.ukf.net/p002.htm

When was 611 Sqn converted to 100 Octane fuel? Nine of them by 21/3/40...

K9963 Ia 176 EA MII FF 4-5-39 602S 8-5-39 AST 27-11-39 611S 4-6-40

All of these Spitfires had engines built well before AP1590/J.2-W was issued, showing that the required modifications on early Merlin IIIs were well in hand on 611 Sqn.
