Very fine. The shotgun retains 60% of the brown finish on the Damascus patterned barrels with some light scratches and marks. Original case colors are present with only traces on the left lock plate but strong retention on the hammers and visible colors on the right lock plate. The upper tang has faded traces of the case colors. The trigger guard and buttplate retain 70% of the fire blue finish with the high edges faded to bright. The blued initial plate on the upper wrist has some light fading. The other components have an aged silver patina. The wood is good with some crisp checkering, some small cracks on the butt, some chips on the upper edges of the forend, and some minor scratches and scattered small dings. The action is excellent and most markings are clear. The case is good with a crack running along the top from the left side to the middle of the case along with some cracks on the lid and minor wear on the exterior along with stains in the interior.
