O G Marsh - Military Medal

[nigel]

I was wondering whether anyone had come across the Military Medal for my Great Uncle, 11604 O. G. Marsh.

O G Marsh was a Sergeant in the 19th Battalion (4th City) and posted missing on 31st July 1917. The Military Medal was awarded for his actions on 23rd April 1917 during an assault on the Hindenburg Line at Cherisy.

This medal has gone missing from the family and we would very grateful for its return or information regarding its whereabouts.
