Stanley Hayes (No.7486) - Service Record shows his enlistment age as 19 years 1 month, but other records indicate his true
D.O.B. as being the 20/05/1898. This would have made him only 16 years old (a few months short of his 17th Birthday) when he enlisted.
Therefore possible that he is one of the younger looking lads on the front row without the flat caps (either 5th from left or 4th from the right).
