Miranda sent me photos of a cut throat razor her father brought back from the Far East as she would like to get in touch with family members of Australian John Robert Leman Church, its original owner.
I have collected as much information as I could and put a page into the Roll of Honour about John:-

In the hope it is seen by a family member.
