U-281: B-24 and Sunderland attack, info needed please

[Joda87]

Good morning everyone,
I need your help to know, if possible, information about an attack that U-boat 281 suffered on 17 October 1943.

According to the logbook, which can be found on the NAW archive (T1022 R3047), at about 12:35 am the U-281 was intercepted by a B-24 and a Short S25 Sunderland. The attack lasted a few minutes, then the Sunderland was shot down by on-board anti-aircraft fire.
The B-24 returned, intercepting U-281 again at about 19:11, dropping a few bombs.

At that time U-281 was in sector AK2488 (central co-ordinates 59°09'00 ‘N, 031°00'00 ’W, North Atlantic, east of the southern tip of Greenland).

Is it possible to know to which wing the two aircraft belonged (and also if USAAF or RAF?), knowing the date and position?

It is a complex question but only this forum can help me...

Thanks in advance!
Marco
