Hello again Phil
Big sis has sent me the details. Hopefully the pictures are attached.
The posed group is a photo which includes my grandad -back row extreme left. Frustratingly the bottom centre part of the picture is damaged and I think this probably held some clue as to where it was taken.
The second picture is a postcard sent to my grandmother which is postmarked
Manchester K 1915 The photograph appears to be attributed to - J Cleworth, Chemist and Photographer, Green Heys(?)
Hope you can shed a little light.
Many thanks for your time and trouble
June
