And you are sure it was after 1951?
There are two Albert E Bunce death registrations at roughly the right time.
Dec 1950 Uxbridge 5f/96 Albert E Bunce age 51.
Sep 1954 Salisbury ( Wiltshire) 7c/412 Albert E Bunce age 53
The first is a little earlier than you thought, the second is in the wrong place!
