Somewhere I remember an aerial view of a Luftwaffe airfield where the following a/c can be seen.
B24, B17, DH Mosquito and beside it a Beaufighter, all had Luftwaffe markings.
There was as said mention of the Beaufighter being gifted to the Croat force but I also recall that a couple of Beaufighter's came down in the then enemy area late in the war and maybe one or more were taken into Croat service , by which I mean that the wrecked a/c were marked with Croat colours as was a B24.
There was a Captured Beaufighter thread on the old LEMB website. I believe that it may now be viewed by members of the newer Luftwaffe website.
