It IS a Fairey Firefly! It could, at a pinch, have been a Fairey Fulmar and had I remembered about that aircraft earlier, I would have been juggling between them both, but that wing gives it away. The little sticky out bit on the trailing edge was not, to my knowledge, present on the Fulmar and the air intakes on the front are definitely FIREFLY-ISH. So that is me committed. You can either confirm, deny or say nowt and continue to tease but I will now retire, having made my firm choice.
