Turnbull did the case colors. This is what they used to called 'mottled' and now call European. Nicely toned down. On my other Martini project I rubbed the case colors back with used pads so that the engraving showed better.

No safety and as you know this is one of the few faults of this action. Fortunately the striker spring tension holds the bolt just high when the action is opened to keep a cartridge from slipping from the chamber so that the rifle can be carried with a round in the chamber until shooting time.

Nice selection of a classic cartridge. Should serve your intended purpose quite nicely.
