I have a brass framed Navy arms Griswold and Gunnison. Except for the markings from the importer on the barrel, there were no other numbers, etc, except on the cylinder. that was where I found the proof house marks, the serial #, and at the back end by the nipples, the Pietta symbol. As far as quality, the Griswold is not the nicest or most expensive gun I have by any means, but it is my most often shot. I just like it.
