Yeah, I figured in a moment it was a staged scene: no visible damage to plane or building! I agree it is probably an old S1S, maybe a homebuilt. May have been sacrificed for this odd use due to some prior damage that made it un-airworthy, which is where the "plane on a stick" thing seems to come from.
I learned akro in an S2B, and it pains me to see any Pitts end up like this.
