Good. Bore is dirty with some firing residues that should clean to Bright. Metal finish faded to primarily brown patina on the receiver with darker brown streaks and some traces of extant blue. Barrel markings weakened by refinish, with some scattered brown streaks and scratches. Stock exhibits handling wear, dents, and mars overall with signs of sanding near butt and gaps around the buttplate. Crack forming through butt at toe. Wobble to butt. Mechanically functional when cycled by hand.
