Here is a WWI Enfield SMLE rifle fitted with the scarce Whitehead mount and a Winchester A5 scope. A one of a kind configuration in the collection world but not the best sniper setup of its time, from an engineering point of view.
1915 Periscopic Prism Company Ltd. Sniper scope, used on Enfield SMLE (serial n° 6133 Y) during WW1. Even if several scope models were used by the United Kingdom during WWI, the 1915 P.P.Co was the most used by British snipers.
