Lots of info on the 91 Spit. Remember it's a Vc not an IX. That profile is based on photos taken in May 1942 at Hawkinge by the Air Ministry of 91 Squadron.
I've got the set of photos in my 91 Squadron stuff.
So here's Bobby Oxspring in the cockpit of that bird. You can see the squadron leader pendant and Nigeria inscription easily. 91 was "Nigeria" squadron.
Two images of the line up of 91 squadron. Oxpring and DL-Z in the head of the line.
