Hi,

I am a new member and I apologize for replying to an irrelevant message but I could not figure out how to address a new message to everyone on this Spitfire forum.

I have photographs of Spitfires on Corsica in 1944 with large, broad, white letters: HNH and HTV on their fuselages.  Does anyone know the squadrons, wings, groups, assignments, etc. for these aircraft.

*Cheers*

In reply to my own question what was the fastest Spitfire Fighter ?.
(Edgar the 450mph @ 25,000ft was for a Spitfire  F22 powered by the Griffon 64 an experimental engine.)
Spitfire F21 PP139 acheived 460 mph @ 25,600ft in 1943, Supermarines figures ,this with the 40ft 2-in w span.
Alex Henshaw  Chief test pilot for Supermarine @ Castle Bromwich quotes a figure of 465mph ' near 27,000ft
in the first production F21La187, again with the 40ft 2-in w span. These aircraft all being powered by the Griffon 61,
which in its early days was a bit temperamental. In late 1944 an F21 was tested against the mark XIV, results
found the F21 being 10-12 mph faster. I , it shows 448mph @ 26,000ft for the FXIV. the F21 with the Griffon  61
 which differed from the Griffon 65 by having a differant supercharger gear ratios which gave slightly more power
@ high altitudes 448mph+ 12 = 460 mph the speed of a standard F21 Spitfire, Powered by the Griffon 85 driving
 contra props it was found by Boscombe Down the A&AEE that these increased max speed by 5mph (465 mph)
 amongst other advantages ,also useing 160 octane fuel pulling 25 PSI boost would add to that figure @ around
 21,000ft
  Little has been of the performance of the late production spitfires i hope this helps.
