The Wood Brothers of Stacksteads

How we can date when three of my great uncles, the brothers, Dyson, Fred and Craven (seated) posed together for a photograph. Sometime afterwards, Lewis and William (inset) were added, so all 5 of them were now on it. During my research, I was able to find out lots of information about all five of the brothers, and as a result I was able to cross reference this information with data from their service records, and looking at what you can see on their uniforms, I was then able to date when the photo was taken. I will also give a brief summary of their war stories.
