Internally is one thing - it's the external aspect that you need to assess.
Is the lettering sharp - and all the edges crisp, or has it been buffed and been left with a 'softened' look?
That's likely the case, and if so, then leave it as-is and use it as a shooter.
On the other hand, it may have merely been tank-dipped, and if everything is clean and crisp and not over-buffed, then get some 'Simichrome' and a soft cloth, and reduce the finish until you've 'silvered-out' the piece.
Without clear, close-up photos, it's impossible to say.
