WebUnlike the Lattey sight, which had a clear lens and mounted in front of the SMLE fore-sight block, this model had a spot reticle, and mounted behind the SMLE front sight, magnifying both the target and the rifle's own fore-sight. A boxed set of Alex Martin's SMLE sights is shown below, and includes a standard BSA No.9C folding target rear sight. WebThe system was effectively a then latter-day evolution of the early "Lattey" design of Galilean sight that. provided First World War snipers with an improved sight-picture over their Short Magazine Lee-Enfield (S.M.L.E.) …
