I found this newsreel which shows Galland and wife arriving in Frankfurt (See the 4:00 mark). You do see Galland and Sylvian walking down the steps from the plane. She is wearing the same fur coat and gloves and carrying a purse as shown in the photo. Another very brief scene shows part of the press conference and your grandfather can be seen wearing the scarf as shown in your photo. There was also a woman reporter in the newsreel but she is wearing a cloth coat
