A Birchall Invalided out of the Great War

This is a common scenario for me. I find another family member’s medal but it’s an orphan. Especially true of the WW1 pairs. I often end up with either the BWM or the VM. Not often both of them. It makes me wonder how they got split up. In this case it’s a humble BWM for John Burchell, T-313914, a private in the Army Service Corps. John was also entitled to the SWB 392607. He was invalided from the Army on under Paragraph 392 (xvi) 2(b)i, sickness. Looking at his discharge papers its apparent his eyesight had begun to fail. His medical report shows a man with numerous wear and tear injuries. I think the Army just wore him out. He was 37 when he was discharged, too old for the game.
