According to the Luftwaffe night fighter claim books, 6./KG 53 scored four night victories in May 1942:
16 May, 2210 hrs: Uffz Mistler claimed a TB-3 near "Borogobusch"
19 May, 0045 hrs: an "Abschuß", no more details
21 May, 0010 hrs: an "Abschuß", no more details
29 May, 2255 hrs: Fw Bauer claimed a TB-3 4 km east of Uschakova
I found today a Russian website with detailed story of the TB-3 unit that was in May 1942 called 1 GvADD, and losses of TB-3 to "enemy fighters" were signaled in the night of 16-17 May (2), 20 May and 30 May. They seem to correspond with above claims nicely. The website is here:

I wonder if a scan of Luftwaffe losses data base can help to complete the names of above claimants (at least Mistler, Bauer will probably return many results).
