I think its that the lower nose profile is too deep.
More reminiscent of some of the Spits that had that profile, I think it was to house a larger cooler of some kind, can't remember.
I just wish they'd give it a 4 bladed prop, 6 exhaust stacks upgrade it to a Merlin 55M. clip it, and release it as a L III. Only scenarios we have had with the Seafire would have used the L III. (good double for the Vc also)
Oh well.
I'll see if I can dig out pic I found again. Showed a whole bevy of L III's on deck, and ALL were clipped.
(oh, workin' on a nekkid nine)
{edit} found it. Seafire LIII's on HMS Hunter
