This is the system I worked out for myself. I've shared it over the last few years, but havenot yet put it into published print.

Dig and similar guys handle enough guns and see enough commerce to develop an intuitive knowledge of "whazit worth?" Those of us who are mere mortals need a "jump start" value guide to get into the ball park on values.

Brand Value must, I say, must be separated from the issue of quality. Trying to associate quality with a name is a dead end. BV1 Makers’ Names – Price Factor = 8
