Does the blue book of gun values include all types of pistols shotguns and rifles?
“ALL” no, but it is a complete as your going to find and darn close. I have one gun myself (US known manufacture no longer in business) not that terribly old that is not present however can find no record anywhere that ever was produced. I will also qualify this if your looking for information/pricing on PRE-1898 firearms this is not the best source for values or details get a copy of Flayderman’s. Also note these values are only a guide, sometimes rare or scarce variations or collector items may not be identified, and strange as it sounds (crazy actually) certainly calibers in rifles tend to bring different values depending if you’re in the east or west.
