The C-47's in A Bridge Too Far are real,that is,those taking off.They do have individual numbers as in J6,J7,or J8.The one you're thinking about is the same numeraled C-47 in Pearl Number.It is seen in the beginning of the movie and about three more times during,including the scene at the end when they come back with his buddie's body,after the raid.
