Hello, I'm a new member to the forum. I have a question about a service revolver that I have. It was my wifes great grandfathers revolver. He was the sheriff of a small town years and years ago. It is a .38 long cartridge by Guisasola Bros. & Co. I've tried to research this handgun without much luck. If anyone could steer me to a website or have any knowledge of this gun, I would be very apreciative. Thank You
