I know from a bit of reading that the Russians weren't too keen on publicising lend/lease aircraft so I have only seen scattered reports on numbers and active squadrons...
Can anyone shed some light on the numbers shipped, numbers of squads equipped, and squad-plane lifetime (i.e. how long did XXX squad fly Hurri B's before switching to La7s or whatever)
I know these planes for sure made it to Russia in substantial numbers:
Spit Vs, Spit IXs, P47(don't know version), P39, P40, Hurri Bs, A20s
Looking for books or websites--anything with the information consolidated for my short attention span

.
Thanks in advance
