The Spitfire with the ring on the tail.

The Spitfire in the video is K9795 and was the 9th production Mk 1 with 19 Squadron. The ring on the tail is a "rudder horn balance guard". But what is it guarding against? Well, apparently, some of the earliest production a/c were fitted with spin recovery parachutes (don't know where they were installed) and the "guard" was there to stop the parachute lines from jamming between the rudder horn and the top of the vertical fin!
