[Csaba B. Stenge]

I am not so familiar with the Bulgarian aviation, but according to my knowledge, the B.135 monoplanes really claimed one B-24 (on 30 March, 1944, when the 15th AAF attacked Sofia) The 450th BG lost one Liberator on that day (from the 723rd Sq, crew of Lt. Clarke). I have just the info, that a tail gunner from one another plane reported the plane falling down without control, but they did not mention attacking fighters (just AA fire). So maybe they shot it down, but maybe not (crashed due to other cause but was confirmed to the fighters) My vote is still a Japanese fighter (but need sb who researched very deeply their Army aviation)
