Hi all
I have found my Granfather's pension records on Anc* and I am so pleased to have these and think

that I understand them!
He was born and lived in Birmingham and served with the West Yorkshire Regiment and Royal Defence Corps and my ignorance of anything military is throwing up so many questions in my mind.
After finding his records, I went to the National archives records online and downloaded his medal record. There isn't a great deal of information...or maybe there is but I do not understand the relevent details

I am wondering why he would serve with the West Yorkshire regiment and also why would he have two numbers?
Can anyone help please?
Thank you so much for reading this garbled message

and I will attempt to attach the record and here is the detail.
Harry Towner
West Yorkshire Regiment, 15545, Private
Royal Defence Corps, 88557, Acting Lance Corporal
