Whilst carrying out our Collections Project at the Royal Engineers Museum we came across this service dress jacket, it is named to Lieutenant Martin and has Lieutenant rank insignia and a Distinguished Service Order medal ribbon. As you can see from the photographs the jacket is badly stained and ripped. While many of the service dress uniforms in the collection have obviously been worn this jacket is particularly interesting as it has clearly been worn in battle. Most interesting of all are the old museum labels attached to it reading 'Do not clean, Flanders Mud' and 'Do not remove mud or stains.' these marks that remain on the jacket from World War One make it a very significant part of the collection.
