One of the reasons for my joining the forum is the ability to network for information. I have a friend, actually I have several, but one in particular has a Model 28-2 and he has asked me for some help. Its a brushed nickle finish, 4 3/4' bbl, issued to the U.S. Marshal's Service. It may be one of only 500, he is not sure. Its NIB, never been fired. Its family, not inventory, and he just wants to learn more about the firearm's history and a fair approximation of value. I've done some looking and asking, I cannot find anything. If anyone has some specific information, I would really appreciate it.
