First Bf110C-7 (factory built - only 39 airctafts) - produced from july 1940 to september 1940.
First 8 Bf110E-2 produced in october 1940, and largely went in series on december 1940.

At the same time, around december, most of survived C-2's, C-4's were repaired and upgraded to C-7, and got it name in official documents.

I accept MG position about Bf110C-4. It was not a main "zerstorer" of BoB, but... It is chosen, and "let it be".
From september 39 to july 1940 there were 359 Bf110C-2 built. Also, ~200 Bf110D-0/1/2/3 were built from march to november 1940. And we must not forget about 50 new Bf110E-1, wich saw operational in october - november 1940 during Battle of Britain. And all these bunch are against "dead-end model" Bf110C-4, produced from may 1940 to september 1940, in number of 155 aircrafts.

I can list a several ZerstorerGruppen, wich operated and lost in action mainly Bf110C-2, or Bf110D, up to 80% of all losses.

See, this is what I meant with well of wisdom. Oleg has it right here at his disposal and he isn't making good use of it, apparently. If he only had asked the right questions prior to the point of choosing the aircraft types and starting their build process ...
