<p>Seven Spitfires make for a stunning sight, but this was only half of the total formation!
Seen here, from top to bottom, are:-
Mk.XVIe 'TD248 / CR-S' (G-OXVI),
Mk.IX 'TD314 / FX-P' (G-CGYJ),
Mk.Vb 'EP120 / AE-A' (G-LFVB),
Seafire Mk.IIIc 'PP972 / 11-5 / N' (G-BUAR),
Mk.Vb 'EP122 / GL-B' (G-CISV),
Mk.I 'R9612 / LC' (G-CGUK and really X4650)
and 
Mk.Ia 'N3200 / QV' (G-CFGJ).
The Spitfire formation and tailchase were the undoubted highlights of the IWM organised 'Meet the Fighters' airshow.
