A re-welcome to you. The revolver is properly known as a 38 Safety, 3rd Model. Ship date would have been most likely 1893-1894.
I believe it may have been refinished in the past. There appear to be dimples around several pin and screw holes which is not how the factory work should look. It also has a grey finish that reminds me of cold blue coloration, but that could be lighting. Lastly, it is very dull, not the fine polishing of a factory gun. No big deal since there is not a great deal of value for the 38 Safety, partly because there were over a quarter-million made and many survived. I only have access to your pictures and a hands on inspection would be required to be certain of the finish.
Forgot to ask if there is a serial number on the bottom of the box?
