I tried correcting that Elizabeth Regina thing a half dozen times, and it never took. I'm going to have to learn how to edit on this forum.

The Lee Speed sporters had a tang safety, which was a purely civilian thing. Your military action wouldn't have the tang, nor the hole through the socket for the safety arm to pass. I'm still thinking the rifle should have had a side safety, but I'll have to look. I have all of Skennerton's books. The target sight was probably this one, the No 9. http://www.rifleman.org.uk/PH_Service_sights.htm If it was a carbine action it should be marked LEC on the left side of the socket, I believe.
