Hi Nick,
You are most welcome. Yes, I think your 'candidate' for January 18, 1945 was 511 ORAP Pe-2, S/N: 15/248.

By the way, the Pe-2 serial numbers were painted on the tail surfaces with a horizontal line. See pic of 511 ORAP Pe-2, S/N: 5/308, which was listed in all of my Pe-2 service lists and most likely survived the war:

October 1, 1944
January 1, 1945
April 1, 1945
May 1, 1945.

On May 1, 1945 her tactical tail No. was '29', engine serials: 41-4916 and 41-4859.

Cheers,
Gabor
