There is only one death listed for a Cyril Edward in England & Wales from 1941 when married. Birthdate would fit with birth registration. But death could have been registered without middle name.

Well the digital copy of the wedding cert has arrived.
Confirmed Cyril Edward Francis (Corporal), 30yrs, married Sheila Elizabeth Gibson (18) 1 May 1941.
His father was John Percival Francis (Hotel Porter).
They were both posted at an RAF base at St Athan. (near Cardiff, Wales.) Also if he held the rank of Corporal then he was not in the Royal Artillery as he would have been a Bombadier.
So more "digging" ahead to identify his death date.
Have you tried searching in the
London Gazette there maybe mention of when Cyril was promoted to Corporal.
I don't know this link will be of any help
