It is a well done sporterizd 1903. The sights are not original but are a very nice addition. The stock looks like a commercial model with checkering from the manufacturer. It could possibly be a Herters stock? If the bore is good the gun is in the 350 to 400 dollar range. The rear sight alone is worth about 75 to 100 by itself. Ask 450 and let the buyer make you an offer.
