I would write down the makes, model numbers, calibers, and good descriptions of the guns in question and then go to Barnes and Noble or Borders and get several of the gun digest or blue books and look them up. You will have to take into consideration the condition of the guns when coming up with a good price.

Also, talk to the woman and see how much she is looking to get out of the guns. Tell her the truth about the values of them and ask her if she would take $$ and make her a fair offer.
