As shown in the photos most items are in very good condition for age.  Unfortunately I don't have any details of the persons name although from badges on his arm you can see he was at Bisley in 1881 and other events so might well be possible to identify him.  I am not 100% sure but I think the younger soldier is the same person when he started his military career in The Royal Warwickshire Regiment (6th Regiment of Foot).
