Thanks.
Interesting how they were able to fit an etched glass reticule to the No71, but not to the No32. There was a trial done in 1944/45 which recommended a modified reticule including a two-thickness crossbar or horizontal wire. The reason obviously was that in low light you can then find the heavier horizontal bar as easily as the vertical post and use the two to align on the target without actually seeing the tip of the post or the crosswire/horizontal bar, as you can with the Germanor No.8 reticule. Some of the WWI German scopes went one better and had a short vertical bar projecting down from the top of the field of view; to be used against the lighter skyline of course.
