Hi Stukapilot,
Sorry that I missed your question. All the action involving IK-3 is described in this book as it is pretty inseparable from the Yugo Bf 109E story. Beside that, the sole combat involving IK-2s is described as well, as it was against German Emils. As for the 351 and 352 Sqn, my article about these units should be published in French (pardon me
) next year. After the second volume of the Bf 109 book, one of the projects I'm involved in is the story of the Balkan Air Force, which will be in English, but this might take quite some time...
Cheers,
Boris
