I got to handle a friend's eighteen ninety eight vintage Holland and Holland twenty gauge today. It is a sidelock gun, and a joy to hold.

But one curious thing was a lever that lay between the top lever and the 2-position safety. It can only extend straight back when the safety is in safe position. The safety cannot be switched to fire without first sweeping it to the side. Is this extra lever simply an additional safety system or does it have an additional function? When would it most likely be used?
