I did. And there is information according to which there were production problems with Merlin XX so they decided to use Merlin X for first batch. There is no information about the engine when Spitfire Mk III was weighted for the first time. The engine is mentioned when talking about second weighing. Another information suggesting that Merlin X was installed in Spitfire Mk III is performance data at the end of the chapter which states Merlin X as the engine.
The span you sugested is ca. 10.3 metres (sorry that I use metric system) while LF versions had less than 10 meters, Spitfire is suggested to have even less than LF versions.
@Andy. Thanks for the hints but I've meant Spitfire Mk III, not PRs.
@Revi16 I know those sites. Interesting but not very helpful.
