Having served in the ranks with the Royal Engineers as Sapper and Second Corporal, and qualified for the 1915 Star, your man was commissioned into the King's Shropshire Light Infantry, 4th Battalion, on 30 Oct 1917 and his commissioned service qualified him for the Victory and British War Medals.[ Had he stayed with the RE he would probably have got these anyway].
Officers had to apply for their medals, as shown on the lower part of the image.
Most of the other annotations are clerical entries relating to the Medal Rolls which are held at the National Archives, not online, which may or may not have anything of interest, but usually not.
Other ranks' medals were impressed with name, number etc, but officers' were not.
