Hi all. The attached photos show some items given to me as a child by a kindly neighbour during the 1960s. Amazingly, they've survived me growing up, having a family, house moves, etc, and now I'm trying to ID them. From Googling I think I have a King's Own Light Infantry (South Yorkshire Regiment) helmet plate (officers?) from 1881 - 1897 (?), eight (tunic?) buttons marked Hobson and Sons, Little Windmill Street, London (1878 -1886?) and two smaller (epaulette?) buttons, all similarly KOLI (SYksR). I'd like to display them, rather than putting them back in a box for another 50 years so any guidance on this would be welcome. Thanks.
