my question is, HOW and WHERE and WHEN did the japanese capture a Lagg-3???? hock:

The Manchurian-Siberian border during 1942-44, when the Japanese and Soviets were nominally neutral towards each other. In at least one case a Soviet pilot defected and took his plane with him. I think there were a couple of other cases where Soviet pilots got lost or suffered mechanical trouble while patrolling the border.
