I disagree because it does show that a .410 Parker CHE is worth more than the same gun in 12 guage and on and on with many different models of discontinued firearms. I agree that the prices are off but we are talking relative value and I think it is the best reference to be found in one volume on guns one is likely to run into. Flayderman's is the best for antiques,many of which not one person in a 1000 will ever see let alone have a chance to buy.
