Overbore A5 mounting during WW1
With the mention of the mounting bracket having been developed during WWI on the advertisement for the Parker Hale Easyfix Telescope Sight Bracket for Service Rifles I am curious if there are any known examples, or at least mentions of the Winchester A5 scope being mounted over bore for sniper rifles?
I was under the impression that all british service rifles fitted with telescopic sights had the off set mounts to allow continued use of iron sights and stripper clips for reloading. This raises questions.
