Nitrox, answers to your questions:
1. Yes, sporting rifle still works on cock on closing.
2. Yes, original safety flag; clears the scope by a hair's breadth.
3. Trigger mechanism is a Recknagel one for Mauser 98 modified for fitting Mauser 96 (don't ask me how, but I'll share photos when possible); the trigger's shape was re-worked for fitting nicely into the trigger guard.

No one asked the question yet but I will mention that the cocking piece (see below) was removed from the action as it brought little value to a sporting rifle.
