Buzz, the process and look-up tables came from market research I have conducted and continue to conduct. The idea was to make myself a "crutch" to get a jumpstart past my lack of experience (and lack of opportunity for experience) with Brit and Continental guns. When I got through all the initial collection of data I found that brand value (BV), original quality grade (OQ), and current condition level (CC) would yield a sufficintly accurate estimate of value. Keep in mind that "value" is what one would predict the market would pay as opposed to "price," what a given seller asks for a given gun. I have found the tables to be useful, as have many others.
Questions?
