Information about a J Saget blackpowder double?

Julian Saget was a gunsmith in New Orleans from about 1860 to 1890. I have a J Saget double barrel that was imported from Leige, Belgium. It has an engraving of ducks on the water surronded by J Saget, New Orleans, LA. It is a 16 guage with 44 inch barrels. I bought it from an antique dealer in New Orleans. Is this similar to your gun?
