My Grandfather served in 153rd Field Regiment RA, in Sextons. Sadly I never knew him, but recently I inherited some of his photos and momentos from his time in the 153rd.
There was a superb website;
www.paoyeomanry.co.uk showing lots of Sextons and crews. Sadly this website seems to have disappeared.
Here are a couple of Christmas cards he sent in 1944, (I'll spare you of what he wrote to my gran!!) and a parade of the regiment being inspected after the war had ended.
