Odd goings on here. The man has to be born in 1905 from all the evidence, so was only 16 when he joined ADRIC. He could not have been an army officer . I have no idea how he got into the ADRIC. He was claiming a 1900 birth when he went off to South Africa in 1923, presumably to be over 21 on the ships papers. He travelled with GH Williams who had also been in ADRIC in G Coy
