109 E1
109 E3
109 E3b
109 E4

E-1 - production began in January 1939
E-3 - production began in late 1939
E-4 - production began in spring 1940 (with the great majority of previous versions being re-equipped with MG-FF/M and relabeled E-4)

In August 1940 the majority of subtypes were already of the E-4 and E-1 type.

Ermm year but just becasue they are in production doesnt mean they are on the front.

So in the BoB they were generally E1 and E4 then?

Correct. There were only 250 E-4 produced in factories but there were a lot more "in the field" since the earlier versions were reequipped and relabeled as E-4. I think Kurfy had some hard numbers on E-1 v s E-3 vs E-4, but I can't find it ATM.

So really its impossible to say when retrofitted aircraft and how many where in front line service... - This will be why I can't find the dates!

Nuts.

Ok what about the allies?

Spitfire IA was retrospectively applied to Spitfires with 8 x .303s when the Hispano IB - started trials with 19 Sqn in July 1940; before that all were Spitfire Is.
First Spitfire I in service was the third off the production line:

So there was only Spit I until July 1940 then they became the Spit Ia? The difference is the prop pitch isnt it? But you mention cannons.

[bolox]

1/1a is purely naming convention to differentiate them from the 1b cannon armed spits, so at a stroke of a pen spit 1 became 1a.
CSP modification is not related to mark #, rather part of ongoing improvements program, but as the 2 occurred at ~ the same time.....
