Here's a very interesting Parker. The seller calls it a "field gun" but I'd be witting to bet it was originally a competition trap or live bird gun. It sports a Miller trigger, a Monte Carlo stock, a modified safety (either pinned or has some mechanism in the tang that affects the safety) but it's too bad the barrels have been poorly "mono-blocked" and the checkering is wrong for a Grade 3. Anyway, it has some interesting features.
