Mallory, I've found a medal card for Thomas Butcher, Royal Berkshire Regiment. It doesn't state much really.
Thomas Butcher,
R Berks R, Private No. 28904.
Lab C (Labour Corps) 245064
Received Victory Medal and British Medal
No Theatre of War or Entry Date given
I've looked through the pensions but can't match one to these service numbers. When soldiers moved to the Labour Corps, I believe but may be wrong, that it was because they became 'unfit' for frontline duties due to injury or illness. They then went to the Labour Corps to be the fetchers and carriers of supplies etc. Maybe Ken would know a bit more about this. It seems he survived the war as I can't find him on CWGC.org
I did find this website which may be worth browsing if you have time, you may be able to match up the shoulder braiding.
