Does anyone know if there was a CSM John McKenzie in the 7th RH. The reason for asking is that I have a large period framed photo of a Royal Highlanders CSM ,written into the bottom Left of the Photo is John McKenzie. On the bottom Right is Gordons Studio Cupar Fife. The person in the photo is not wearing any medal ribbons, I have asked the same question in the Great War Forum, sorry for poor photo .323E9046-1782-4609-8818-47976AE5B36E.jpeg
