I have a very similar L C Smith 20 gauge. I inherited it many years ago and have no idea of it's value. The noticible difference is in place of the bird dog you show, my L C Smith has a quail on one side and a duck on the other. There is a number on the trigger guard, 680. Do you have any advice about what it should be insured for? It'll stay in the family, so I have no interest in selling. Thanks, Ted Arnold
