Beaufighter , it is:)
I am not 100% certain if it is a "1C", I have a larger Image of this and In it you can see the red dope on the wing guns openings clearly. This is one of my favorate pics of this plane, My gues is malta as well. Somtimes I wish we had goten a Beaufighter instead of the Mossie, always liked it for some reasion:)
