From forum member Lee Stevenson.
"Just wanted to say that I actually made/hand carved that headstone/marker back in 1993...
We held a small service at the grave side attended by Robson's grand-daughter and the late Colonel Mike McCabe, RE, and members of the local RE Association in attendance.
I have some photos of the original plaque and of the service.
The wooden plaque was replaced by a permanent stone marker in 1999"
