It isn't the side lever like the picture SDH had on the cover of Precision Shooting Magazine (search this site for Westley Richards Deeley & Edge). Mine has an underlever similar to a Farquharson, only much more streamlined and less gangly when opened. The trigger stays with the action when opened and there is a "safety" lever that feels like it blocks the trigger and locks the lever.

Pictures will follow tomorrow. Got busy blueing last night and didn't fool with the camera.
