Many thanks & apologies to others who have commented, I found it impossible to make head or tail of where/who I should ask my question:

It would seem there is more than 1 actor called Colin Campbell, my father born in 1937 was indeed in a television program called A Family at War where I noticed the deletion, he is still alive but not too well so finding this was upsetting & incorrect.  He also had a role in The Leather Boys if that helps to identify him

Thank you again for your assistance & hope I'm writing to the correct person!!  I will also try to contact Kuru
