Alex,
A single reference to "
the old Anson" in use by 318 Squadron is made in this personal diary:
http://www.polishsquadronsremembered..._318diary.html just above 16 September (1944).
The two F/O's mentioned were with same squadron.
If accident of 11 Dec 1944 was on same airfield as 318 Squadron was, then unfortunately no report of it in this diary.
Regards,
Leendert
