Eastern Front nightfighter claims vs Soviet losses

[Nick Hector]

I thought it might be interesting to share and swap info on this very under-documented and rarely discussed aspect of WWII aviation...

22.4.42 Lt. Horst Hannig of 5/JG 54 claimed an R-5. Was this actually Yakov Shutov Ageenko of 699 ThAP (NBAP?) KIA, date of death given as the previous day?
24.4.42 Max-Hellmuth Ostermann claimed an R-Z. Was this the aircraft of 662 NBAP shot down by Bf109s this date? Piotr Dmitrievich Severov KIA
19.8.42/0429 Ofw. Fritz Gammel of 3/JG 53 claimed an R-5, believe this was likely from 765 NBAP. Crew of Ml.Lt. Alexey Ivanovich Bushin and Ml.Lt. Alexey Evdokimovich Sergienko failed to return
16.10.42. Ofw. Teige of 6/KG 53 claimed two U-2s. 662 NBAP. Appear to be legitimate victories. Vasily Nikolaevich Borodushkin of 168 SUP said to have been KIA by fighters this night
17.4.43/2154 Fw. Melschert of 10(NJ)/ZG 1 claimed a DB-3F. Was this from 8 GAPDD? Crew of Gen. Mikhail Nikolayevich Urutin Navigator-Colonel Hevesi Akos Akoshevich and shooter-guard radio operator Sergeant Aleksandr K Garankin were shot down by a fighter this night.
19.4.43/2102 Oblt. Erwin Mangold of 10(NJ)/ZG 1 claimed a PS-84. Believe this was from 102 APDD, navigator Nikolay Yakovlevich Tsidilin failed to return this night. Does anyone have any further details?
15.5.43 Ofw. Josef Kociock of 10(NJ)/ZG 1 claimed 3 PS-84s and an "SB-2." Did he actually damage the TB-3 flown by Nikolai Alexeyevich Bobin (HSU), which crashed back at its home airfield?
12.6.43 Oblt. Erwin Mangold claimed a "TB-4" and a DB-3F. Could this pertain to a loss dated 13.6.43, which is of a Li-2 from 3 APDD, crew of Kapitan Aleksandr Ivanovich Sukonkin (WIA) hit by flak, then nightfighter 45km from Karachev, all POW after 8 day's trekking through German territory
19.7.43. Puetzkuehl and Weiss of IV/NJG 5 claimed PS-84s. 102 APDD is listed as having lost at least one crew (that of Fedor V. Spitsin) the night before (date in error?)
12.8.43/0140 Hptm. Alois Lechner of 1/NJG 100 claimed a PS-84. Believe this was from 102 APDD, Crew of Lt V. P. Tsigenko
9.5.44 Oblt. Guenther Bertram claimed 2 x PS-84s. Night's Li-2 losses include 102 APDD, Boris Varfolomeevich Burkanenko WIA and rest of crew KIA on raid to Tapa Railway Station, Estonia
