I think this is "III"; HQ P-47s had the Group insignia on, at this time (Nov. 1944) the c/o was Col. A L Evans and this is thought to be the only P-47 with the Skull.

His Deputy Lt. Col. Stanton Smith Jr. had similar markings on 42-27447 no.79 "KAY P", (minus the skull ?) another of the many D-23-RAs.
No. 93 in photo 1 was flown by Capt. Wheeler; the rabbit was replaced by a bear in the badge, as being more aggressive.
