Best I can do by taking the order of battle for the MTO Air Command and adding the dates the IX or VIII made their appearance with those Spitfire Squadrons. Hope it helps. I realize this is mid 43 but its the best I can come up with at the moment.
Order of Battle is from "Royal Air Force 1939-1945, Volme II The Fight Avails" by Denis Richards and Hilary St. George Saunders.
Mk IX entering squadron service dates from "Profile 206 Supermarine Spitfire Mk IX" By Peter Moss and Len Bachelor
From the order of battle MTO Air Command 10 July 1943
