Depending on who the writer is, Ithaca started making doubles sometime between 1880-1883. They had serial numbers from the very beginning. There were several models, Baker, Crass, Lewis, Minier and Flues, usually named after the individual that made a significant improvement.
Side-by-side shotguns are still manufactured.
If this is an old side by side it would be a Baker model made in 1886. Serial numbers of Ithaca shotguns for that year were 2448 - 4101.
Shotguns break open, not over. Winchester, Stevens, Ithaca have made 410s
Ithaca Gun Company of Ithaca, New York was the manufacturer. "Flues" refers to the designer. These double barrel, two-trigger, side-by-side shotguns were made from 1908 - 1926. Check out http://ithacagunrepair.com/page5/page23/ for a list of serial numbers by year of manufacture.

I don't know the answer, but I know where you can find it. Check your library for "The Ithaca Gun Company - From the Beginning" by Walter Snyder. There's a list of serial numbers that are verified as being Ithaca shotguns owned and used by Wells Fargo Company. Since thousands of cheap shotguns have had fake WF&Co marks added, about the only one's that will bring a premium from advanced collectors (of firearms or Wels Fargo memorabilia) are the ones listed there.
