I am looking for any information about the soldier in the above photograph. I have two of the same soldier. This, the later photograph was taken in 1940. The gentleman was known as Jack and was in the Royal Norfolk Regiment and was last known in the Great Yarmouth area. We believe, but cannot be sure, that he may be a relative. Please get in touch if you can help. I can be contacted on email at allison.cross@hotmail.co.uk
