Hi Nigel,
Roland Dixon’s service number, 77457, was issued relatively late in the Great War. Similar numbers were issued to a conscript in 53rd Bttn in March 1918, a man transferred from S Wales Borders (Jan 1918) and a man who had enlisted in 1916. Roland was born 10/12/1896, so he was liable for conscription in 1916, unless he had already volunteered. I’d be guessing to suggest when he enlisted or arrived overseas. The only casualties in the Manchesters number sequence were May 1918 onwards.
A large draft was transferred from the Manchesters to 1/5th Bttn Borders. I’ve found 2 service records to suggest this was in March 1919.
Welcome to the forum.
