I believe this is Clarence William S. Brinkworth, born December quarter 1888 in Nottingham, the son of Alice Mary Smart and William Henry Brinkworth. Apart from the 1891 census and FreeBMD birth and marriage registrations this is all the detail I have. The age is wrong but he wouldn't be the first young man to put his age up to join the services.
