Keith Chatto on Sons of Bushido

This is Keith Chatto's cover to Page Publications' War in the Air #1:

The cover art is based on MV Features' Action War Picture Library #16:

Sons of Bushido was subsequently reprinted in the following Page Publications issues:

Wartime Library #6 

Air Combat Library #2 

War in the Air #3

Air Battle Library #3 

The covers to Air Combat Library #3 and War in the Air #3 appear to be loosely based on the splash page to Sons of Bushido:

I daresay there are more such Page Publications reprintings of this story to be unearthed.
