Here's what the impact site of a T-6 in an inverted spin looks like.

USAF instructor with an Italian trainee in 2019, out of Sheppard AFB. Two successful ejections on this one.
Somewhat different looking than the Foley site.
edit: Command ejection, ISS selector has to be in the both position.
edit: T-6A/B is not prone to flat spins, all are generally quite nose low.....upright, inverted or progressive ones.
