I'm hoping the TNF collective might be able to throw some light on A G Goodchild, active late 50s (and possibly much earlier and later)
My search on TNF gave me precious little, but then Tim might pluck something from within that I failed to dig up.
The best I could find with google help was an A Goodchild on the Imperial War Museum site

Thank you for any clues
