Synthetic.
I thought so too. But when you take into account the Hurri's wheels are almost touching when in their wells and when extended they are angled straight down, then the wider attach points on the Spit and the splayed legs equals not a lot of difference in track.
I will make a couple of telephone calls tomorrow to a certain two people at Duxford who can give us a definite measurement of the early Spits wheeltrack.
You don't think this could be just a piece of 1940 Spitfire snobbery that has been perpetuated for 70 years?
