Not sure if this is the right place but here goes. I inherited a S&W 357 Highway Patrolman model 28-2 revolver from a family member that passed away and I'm trying to determine its worth. It has a serial number N17x805. I put x in the 4th place because I couldn't determine if it was a 9 or 0. It is in very good condition and looks like it has not been fired often. If you guys can help me out with this I would appreciate it.
