So the idea of using Fighter Command for guiding ac towards bogies originally arose from guiding non radar 'Cats's Eyes' RAF Defiant and Hurricane Night Fighters to targets. The 2 videos here are examples of a Hurricane and a Defiant MkI. The Hurri should not be cannon mounted but AFAIK we don't have a NF skin with machine guns. I didn't show much or any of the combat and in the case of the Defiant, I ran into the belly of the He111.
