Add the FR.XIV and unperk the 14 we have now.
Bubble canopy made no difference to overall performance.
Should have been remodelled as a low-back XIV just to make it look different from the other Spits.
All we need for a complete (barring rarities) Spit line-up now -
Vc - Clipped, Cropped, Clapped.
XII - First production Griffon Spit
XIV - Changed to a low back.
F.21 - Ultimate wartime Spit (perk F.21 and unperk XIV)
Seafire LIII or LIIc
