Yes, you may, Cadet.
Mike, if you want a copy, please let me know. It is a model that fairly accurately predicts average pricing on Brit and Continental guns. You need to feed it Brand Value level of the maker's name (information included), Original Quality grade (a simplified explaination included), and Current Condition level ( simplified definitions included). It is intended to jump start an understanding of why various guns may have differing values. A guy, like, say, Dig Hadoke, who handles thousands of guns a year will have a better intuitive pricing ability. However, most of us never get to see, much less handle, guns like Dig does. So, we need a little "cheater" paper to help us out.
