Hi there folks,
The letters were to designate the armament in the wings, as follows:
A - 8 machine guns
B - 2 cannons and 4 machine guns
C - universal wing which could receive A or B armaments
There was also other letters of reference. As follows:
LF - Low altitude fighter (these are the spitfires with the clipped wings, but I'm not so sure)
F - medium altitudes
HF - High altitude fighter
Bye,
Gustavo

Gustavo, You are right about A,B & C type wings. However modifications LF and HF differed only by engine, i.e. the LF could have normal or clipped wing. Of course, clipped wingtip helped to improve manoeuvrability at low altitudes, but the wing tip was fitted witg bolts and easily changeable.
I have little if no knowledge about E wing, but some sources claim, that it had 2*.50cal machineguns instead of 4*.303's and the usual 2*20mm cannons.
P.S. I have read an interesting fact. When Supermarine staff started developing cannon armed Spitfire, they have tested 8 (!) cannon armament. When the test pilot fired all 8 guns in flight, kickback almost completely stopped the airplane :) He hardly saved it from crash.
