Just to recap I think it was probably taken around 1915
Sapper is his rank = to a Private Soldier
RE = Royal Engineers
No. 1869 His Army Number
2/7 (or 217) probably 2/7 Comp - is the Company, within the Battalion, within the Regiment, but I'm not totally sure the Royal Engineers had Battalions.......perhaps someone else can put us straight on that.
It would appear that he survived the war, as I could not find him on The Commonwealth War Graves Commission Web Site. A thorough search of the Medal Cards website Annie gave you the link to should establish if he went to France, as a rule of thumb, if he has no card he did not go ( but it's not conclusive).
Winchester Library might be able to help regarding Pitt, but it would appear that today most of the area around the hamlet is a golf course.
I looked it up on Multimap.com
