The jog in the boss between the top tang and trigger plate is to allow room for the sear tips and trigger blades. They just barely clear. The boss is just part of the Fraser take on a boxlock and it is secured with screw both top and bottom. Yes, coil spring for the safety. Not something I have seen on other Scottish guns.
