So far it looks that on January 4, 1945 the 17 VA lost:

20 IL-2m3
1 A-20G-25-DO Boston
1 La-5F
4 La-5FN
1 Yak-1B
2 Yak-9D
1 Yak-9T
1 Pe-2

(Some small, secondary 'satellite' units might be overlooked.) Looks like Szentgyörgyi-Tóth-Szabó claimed 3 'real' La-5 victories as three La-5s of 17 VA, 194 IAD, 530 IAP were lost in their reported area. In fact all 5 lost La-5s belonged to the 530 IAP. Note Lipfert's La-5 victory in prev. comments too. That plane was the 4th (pilot: KIA). All details are known for the losses, except not sure who claimed which particular plane in the battle.
