I would like to add a few words.
I've known Stan for many years, most of them prior to him setting up a gunsmithing business.
I have been in his shop, and taken some of his valuable time while he was gracious enough to show me around. He has also over the years put a great deal of time and effort into this site and into furthering the knowledge of the home gunsmith.
I know nothing of any specific agreement made with him. I do know that he is an honorable man and does conscientious work.
