SEAC (South East Asia Command) was the Allied body in charge of military operations in Southeast Asia in WWII. I came across a model of a Spitfire with the SEAC blue-in-blue roundels: a Mk XIV Spit, with a five-bladed prop, and clipped wings. Being a Mk XIV, it's currently the most recent Spitfire in the collection.
As far as I can work out, this is a picture of the actual plane. It was flown by James 'Ginger' Lacey, based at RAF Selatar, Singapore, in late 1945.
