Hello I believe I have a photo of Captain Alexander (Sandy) Hunter with my grandfather in Kashmir. Feel free to email me and we can exchange information. I too would like to find the family of this fellow, to give them this picture but also to see if they might have any pictures of my grandfather as well. My grandfather mentions him in at least one letter. He would have been in Kashmir in August '42 with my grandfather.
