I received the following response from the RAF Museum Hendon
In response to the suggestion that Hurricanes that forced landed in Belgium during the period 3/9/39 to 9/5/40 were transferred to the Aeronautique Millitaire Belge the Museum noted thatUnfortunately we do not appear to have copies of the Form 78s for Hurricanes L2105- L2111; other sources suggest that these aircraft were diverted to the Belgians before they were taken on strength of an RAF unit which may explain the lack of movement cards.
There is no indication that Hurricanes L1616, L1628 and L1813 were transferred to the Aeronautique Millitaire Belge in our records.
