Here's a previously unknown, at least to me, sight for the M1905 Ross Rifle. I saw this while perusing gun sales on an online website, made by BSA Martin which is a collaboration I'm unfamiliar with. Martin made Galillean foresights for MLE and SMLE rifles at one time according to Rifleman.org side menu - animated with patents taken out in 1910 and 1915 for same which was after M1905 production ended. It appears John Martin of Glasgow is the Martin named on the sight but details are scarce other than for his Galillean sights. The base might have been made by others as there was lots of concurrent activity regarding sights for the various Ross rifles at that time. One sight base, which looks very similar (P. 258 The Ross Rifle Story) was developed by John Humphreys, a full blooded Cowichan Indian tribe member who owned a shop on Cordova Street, Vancouver, B,C, Canada. He never patented his sight base which would have allowed others to copy it. In any event, this is an interesting and apparently little known sight.
