I have some First World War sniper scopes but one that could be called vintage maybe is a Bushnell Scopechief that I have. It has an illuminated center dot (not very effective) I don't know its age but someone may be able to enlighten me there. An old German 'Oigee' 4X scope that must be from the 1950's at a guess (that I hope to fit to a Rook Rifle one day) and I still use a couple of Pecar of Berlin scopes on two of my rifles. One of those old WW1 scopes by Aldis dated 1916 is as clear as crystal the other by the Prismatic Periscope Company has seen better days. The latter only saw use right at the end of the war. Some of those older scopes were certainly built to last! Lagopus.....
