Hi Marie,
You haven't said when you think Edward may have died. When you say "pensionable age", I assume you mean 60+ which implies he died in the 1910s or 1920s. Correct?
Don't be misled by the age shown in a death cert (or listed on the index). Normally the age is accurate or about right, but it can sometimes be hopelessly wrong - particularly if the informant didn't know the deceased and had to guess. In this case, the informant would have been the coroner (if there was an inquest) so you may have found the correct one anyway!
Coroners reports are rather hard to get hold of. If memory serves, these were essentially private documents and there was no legal requirement to have them archived. (I stand to be corrected.)
Given the circumstances you describe, it's possible that the death/inquest was reported in a local newspaper. Perhaps someone could provide you with some guidance about that.
Hope this helps
Dave
