Its pretty clear that the E1 and E4 were the most common variants by far and that around SEPTEMBER sometime, the E4 became more prevalent than the E1, which had been the most common type until then, but even it October a third of the losses were still E1's.

which makes the E3 choice mystifying to me.

Yes, this is the reference I was talking about. He was always complaining that they had old types and the only new ones went to Galland. He did get an upgrade towards the end if I remember.
