Interesting about the Spitfire in Post #380. It looks like its being serviced by an American so assuming its an American Spitfire, the squadron code possibly WR✪. Note the name "Stormy". Now look at the name on this French Spitfire from No. 340 (Free French) Squadron RAF, squadron code GW⦾ ...André Gibert and his Stormy — Historic Photographs | 1943 | people | Spitfire Mk.

The elevators were changed, I think from the later production Mk.V, or perhaps mid-production Mk.IX, to incorporate a mass balance, which gave the "double step", angular appearance, as seen in the photo. The drawing has failed to include this.
Alrighty then. It took a while but I found this, the first 100ish were manufactured from the Mk.V airframe, hence the angular elevator I'm used to seeing. The last 45ish were manufactured from the Mk.VIII airframe with the more squared off elevator.
Sounds about right, and the first had fixed tail wheels, whilst those from the Mk.VIII batches had retractable tail wheels. Got the info on file somewhere, showing which serial numbers were which etc.
