Code on a Beaufighter!
 

Hello!

I am searching the code on the beaufighter flown by Squadron leader J.G. Topham(DFC) and F/O W. Berridge, when they on the night between the 7. and 8. May 1942 shot down a german bomber near Brighton.
Sorry if this is a needle in a haystack but hope for some help here since i would like to build a model of this Beaufighter.
Thanks in advance

Christian
