After looking at the He 111 in the link provide by Laurent and the data from Matti it looks like maybe the 7./KG 4 He 111's with 80% and 30% damage ran a foul of the 49 IAP.
But there was also a large formation of He 111's attacked in the Ulyanovo area by four 2 GIAP pilots. St. Lt. Nikolay Petrovich Pushkin He 111 (his 3rd victory), St. Lt. Fedor Mikhaylovich Lebedev He 111 (his 1st), Ml. Lt. Mikhail Evseevich Ryabtsev He 111 (his 1st) and Ml. Lt. Trofim Grigorevich Kalinin (Unk. if he made a claim but he went MIA 07 Feb 44). The first three all received the HSU during the war.
