Hiya Steve, and welcome back to the forum. Your relative was certainly an original 17th Bn Man as he is somewhere on the photo (click to enlarge) that was taken sometime early 1915 in Heaton Park where the Pals Battalions did thier initial training. The 17th Battalion transport section left Southampton on the7th November 1915, landing at Le Havre the same day. The Battalion followed the Day after, landing at Le Havre on the 8th/9th. The 7th (Service) Battalion,South Wales Borderers landed at Boulogne on the 6th September 1915-so that would fit in with the date he arrived according to his medal card ?. We need someone with the medal rolls of the 17th Battalion to see if he was awarded his 1914/15 star with the Manchester's or the South Wales Borderers. Hopefully, another forum member will be able to have a look for you.
