^ I wonder how they ended up using the same name of the design that we usually identify as Spitfire. Type 224 was quite different.
The name suggestion came from the Chairman of Vickers (Aviation) Ltd., Robert McLean. Reportedly, R.J. Mitchell disliked this appellation and it was dropped from use for the Type 225. However, Sir Robert was in a position to reassert his name preference for the Type 300 ... by which time Mitchell was probably too ill to continue his objections.
Also, as I understand from what I've read, at this time, a name could be proposed, but would not be adopted by the RAF until a production order was placed, or was expected to be placed . . .
Also, I've also read, somewhere, that when the 'real' Spitfire was named, Mitchell's response was 'that's the sort of bl**dy stupid name they would give it', or words to that effect . . .
cheers,
Robin.
